Tokyo, Jul 30: Debutant Lovlina Borgohain (69kg) assured India of their first boxing medal at the ongoing Olympic Games when she upstaged former world champion Nien-Chin Chen of Chinese Taipei to enter the semifinals here on Friday.
The 23-year-old Assam boxer prevailed 4-1 to make the last-four where she will square off against reigning world champion Busenaz Surmeneli of Turkey, who hammered Anna Lysenko in her quarterfinal bout.
Borgohain, a two-time world championship bronze-medallist, displayed tremendous calm in the face of a plucky opponent, who had beaten her in the past.
She was aggressive to start with, followed it up with a tremendous counter-attacking game and kept her defence tight in the final three minutes to emerge triumphant.
The youngster, who was laid low by COVID-19 last year and missed a training trip to Europe because of it, let out a huge scream after the referee raised her hand, pent up emotions finally getting the better of her.
India's previous boxing medals have come through Vijender Singh (2008) and M C Mary Kom (2012). Both of them had won bronze medals and Borgohain would look to better that.
Earlier, Simranjit Kaur (60kg) lost to Thailand's Sudaporn Seesondee in the pre-quarterfinals to make an early exit from the Games here.
The 26-year-old Indian, seeded fourth, went down 0-5 despite a gritty performance.
She was impressive in the opening round and seemed to have caught Seesondee on the back-foot with her measured approach, sticking to a counter-attacking strategy.
However, the judges ruled unanimously in favour of the Thai, causing Simranjit to be a tad reckless in the second round.
The Indian paid for the hyper-aggressive approach in the first few seconds itself when Seesondee managed to connect some eye-catching left hooks.
The defensive errors in the second put paid to Simranjit's chances and even though she gave it her all in the third round, it needed nothing short of a demolition job to get over the line.
However, that was not to be as she bowed out following a unanimous verdict.
The 29-year-old Thai is a two-time world championships medallist and also won a silver in the 2018 Asian Games.

Bengaluru: A soil scientist, who has studied tropical lateritic soils, has released a note in anonymity, warning the Special Investigation Team (SIT) probing alleged mass burials in Dharmasthala (1994–2014) that improper excavation could permanently destroy critical forensic evidence.
The scientist cautioned that in the coastal, high-rainfall environment of Dharmasthala, bones from older graves are often not visually present due to the region’s acidic laterite soil, which accelerates decomposition. “In these conditions, the visual absence of bones does not mean there was no burial,” the expert stressed. “Chemical and microscopic soil analysis may be the only way to detect older graves.”
According to the soil scientist, Dharmasthala’s lateritic soil has a pH of 4.5–6, is porous and rich in iron and aluminium oxides, and is subject to over 3,500 mm of annual rainfall. These factors together cause rapid bone mineral dissolution and collagen breakdown. “In as little as 15–20 years, complete skeletons can be reduced to just teeth, enamel shards, or micro-residues,” the scientist said.
Drawing on comparisons with Rwanda, Cambodia, Sri Lanka, and Srebrenica, the scientist estimated that:
- Graves less than 15 years old have a reasonable chance of yielding skeletons.
- Graves 15–20 years old may yield only partial skeletons and teeth.
- Burials older than 20 years often retain only chemical signatures and microscopic fragments.
“In Dharmasthala’s soil, the probability of finding a full skeleton after two decades is near zero,” the expert said.
‘JCBs will destroy what’s left’
The soil scientist was particularly critical of the use of heavy machinery in the investigation. “Uncontrolled digging with JCBs can obliterate brittle bone fragments, erase burial stratigraphy, and mix burial soil with surrounding soil, diluting chemical signals,” he warned. “It’s equivalent to destroying the crime scene.”
The scientist emphasised that disturbed lateritic soil can quickly resemble undisturbed ground, making it almost impossible to detect graves later.
GPR as a map, not a microscope
The expert also noted that Ground Penetrating Radar (GPR) could play a limited role in the investigation. “GPR can help locate soil disturbances, but in wet, iron-rich lateritic soils, it cannot ‘see bones.’ For burials decades old, chemical analysis of soil is far more reliable,” he said.
Call for controlled forensic exhumation
The soil scientist urged the SIT to stop all mechanical digging and adopt a forensic protocol:
- Use GPR or other non-invasive methods to locate anomalies.
- Excavate in small, measured layers under forensic supervision.
- Collect soil samples for chemical and microscopic analysis.
- Sieve soil to recover micro bone fragments and teeth.
“Only a controlled, scientific approach will preserve what little evidence may remain in this environment,” the scientist said. “If these traces are destroyed, the truth about the alleged burials may never be proven.”
The SIT is investigating allegations of mass burials linked to the disappearance of individuals between 1994 and 2014 in Dharmasthala. No official response to the scientist’s concerns has been issued.
