Lucknow, May 8 : The Lucknow police have solved a three-month-old murder mystery with the detention of a 13-year-old girl and her boyfriend.

The minor girl and her 19-year-old boyfriend are guilty of killing her landlord, who had been harassing her for a long time in the Wazirganj area.

'The accused were identified as Bunty Kashyap and his minor girlfriend. They will be presented before the court. A case of murder under Indian Penal Code (IPC) 302 was already registered in the matter,' said ADCP West Zone, Vishwajeet Srivastava.

'Police have also seized a weapon which they used in the killing,' said the DCP, and added that the case was worked out by a team of ACP Chowk, Raj Kumar, station house officer (SHO) Chowk, Dinesh Mishra, and the crime branch.

According to police, the body of Shyam Chandra Gupta, 56, was found in a drain in the River Bank Colony in the Wazirganj area on March 3. The deceased's son, Ankur Gupta, had lodged a missing complaint, following which police got involved in the case.

The minor girl slashed his throat, and then the body was stuffed in a bedsheet cover and thrown into the drain behind the house, said the ADCP.
