Kolkata, July 29 (IANS): Dissatisfied with the Kolkata Police for calling the mysterious death of Aabesh Dasgupta an "accident", the family of the teenager on Friday knocked on the doors of West Bengal Chief Minister Mamata Banerjee seeking justice.

Aabesh, 17, was found lying in a pool of blood on the ground floor car park of well known writer Amit Chaudhuri's apartment complex in south Kolkata's Ballygunge, where he had gone to attend a birthday party on July 23.

A blood soaked neck of a broken bottle was recovered from the spot.

While the family has been claiming that Aabesh was murdered and the police registered a murder case, investigators on Thursday, citing circumstantial evidence, ruled out any foul play or conspiracy and suggested the death could be accidental.

Based on CCTV footage, the police have claimed that Aabesh tried to jump a ramp in the parking lot while holding an alcohol bottle in his hand.

While jumping, he tripped and fell on the broken bottle and suffered an injury to the armpit, resulting in profuse bleeding which ultimately caused his death.

Police, however, have said their findings are still inconclusive.

The Dasgupta family, which has been claiming it to be a "pre-planned murder", dubbed the police's 'accident' theory as an attempt to cover up and met Chief Minister Banerjee on the day.

"We told her (Banerjee) that there are still many unanswered questions, many loose ends. She gave a patient hearing to all our apprehensions and assured the truth will be unravelled," Aabesh's mother Rimjhim Dasgupta said after the meeting.

"The Chief Minister said whatever the police have said needs to be proved. She assured us that everything will be done to ensure justice," added Dasgupta. 

Besides arresting three people for selling liquor to minors, the police has interrogated the teenagers accompanying Aabesh on the fateful day as also writer Chaudhuri.
