The wife of a civil supplies official, on a 12-day-long dharna here alleging that he was murdered for exposing irregularities by high level officials in the department, has been arrested.

Ms. Selvi, wife of 45-year old Murugan, who allegedly committed suicide by consuming poison, and 25 others who had joined her in her protest were arrested yesterday for continuing their protest demanding a proper probe despite the government ordering a CB-CID inquiry.

As Murugan’s family had refused to accept the body, it was buried by corporation staff in the presence of district officials here last evening, officials said. None of the family members of the deceased were present.

Murugan, an Assistant Quality Control Officer of the Civil Supplies known for his ‘integrity and honesty’, had allegedly consumed poison on September 7 and died four days later without responding to treatment.

His wife had refused to accept his body for performing funeral rights. She suspected her husband was forced to drink the poison for exposing high level irregularities in the department.

Officials said that before the arrest of Ms. Selvi, she was served an ultimatum to accept the body before 3 pm yesterday failing which it would be buried by corporation staff.

Chief Minister M. Karunanidhi had announced a compensation of Rs. two lakh to Ms. Selvi and also ordered the transfer of the case to the CB-CID Police.
