Agartala, May 13 (TIWN / IANS) After a month-long students' agitation, Tripura Police on Friday night arrested a trader in connection with the mysterious death of his niece and engineering student Anwara Chowdhury, police said on Saturday.

"After receiving the post-mortem examination and forensic reports of Anwara Chowdhury, we immediately arrested Noor Mohammed on suspicion of his involvement in the death of the student," West Tripura district police chief Abhijit Saptarshi said.

Noor Mohammed, a contractor-cum-trader and maternal uncle of Anwara Chowdhury, 16, was presented in the Chief Judicial Magistrate's court, which remanded him to two-day police custody.

The officer said that according to the post-mortem and forensic reports, poison was found in Anwara's body.

Since April 10, when Women's Polytechnic student Anwara Chowdhury died mysteriously at Govind Ballabh Pant Government Medical College and Hospital, student wings of the ruling CPI-M, Trinamool Congress, Congress and the Bharatiya Janata Party had been agitating to press for the arrest of the culprits.

The unrelenting students' agitation forced the authorities to exhume her body from a burial ground and conduct autopsy and forensic examination.

Student leaders have demanded stern action against the doctors of the medical college.

They have also demanded that Noor Mohammed's wife and his daughter be arrested over Anwara's death.
