Agartala, Nov 2 (IANS): In a gruesome case, a man strangled to death his 70-year-old ailing mother while another man shot dead his wife in Tripura, police said on Monday. Both men then killed themselves.

Joydeep Chakraborty, 51, a government official, killed his mother, Jyostna Chakraborty, who had lost her memory and was unable to move since meeting with an accident 21 years ago, a police official said.

"Chakraborty then committed suicide in the same room at Badarghat" on the outskirts of Agartala, the official added.

Chakraborty, also a cultural activist, apparently committed the murder as he regularly quarrelled with his wife over his mother's nursing, the official said.

In the other incident, a Border Security Force (BSF) trooper, Surinder Matti, 27, shot dead his wife Khushi Debnath, 24, with his service rifle at the BSF camp at Phatikcherra in western Tripura on Sunday night, the official said.

Police said the killing may be due to some family feud. The assailant's first wife lived in Assam.
