Aligarh (Uttar Pradesh), Aug 13 (TIWN) Two orphaned siblings, whose father recently committed suicide, have threatened to commit suicide if those responsible for driving their father to take the extreme step are not booked.

The brother, 16, and his sister, 15, had lost their mother in 2005.

Their father Krishna Dutt Sharma, 38, a fourth-class employee at Sri Gandhi Smarak Inter College of Aligarh, had allegedly committed suicide on August 3 by consuming poison.

Before he died, Sharma had apparently told his relatives that his college principal and clerk were demanding Rs two lakh to release his salary. They were allegedly giving him half his salary and also not letting him mark the attendance.

He also shot a video while consuming some poisonous substance and uploaded it on social media.

The Aligarh Police, on Wednesday, registered an FIR against unidentified persons under section 306 (abetment to suicide) of Indian Penal Code (IPC).

However, no one has been arrested in the case so far.
