Hyderabad, Jun 22 (IANS): Police in Hyderabad have formed special teams to identify the body of a woman which wrapped in a plastic cover was found floating in a lake.

Sanathnagar police under Cyberabad Police Commissionerate on Monday registered murder case against unknown persons and intensified the efforts to identify the body, which was found floating in Sunnam Cheruvu on Saturday.

Three special teams were constituted to crack the case. Since the body was decomposed, the police released a photograph of her right hand which bore a dollar sign tattoo.

Inspector Chandrashekhar Reddy said the locals informed the police about the body floating in the lake. The police personnel, who rushed there, pulled out the body and found it to be of a woman.

The woman, believed to be aged between 30 and 40 years, was wearing kurta pyjama.

The official said the body had decomposed and the face was beyond recognition. Police suspect that the body might have been dumped in the lake 3-4 days ago.

The police found the woman's limbs tied. They also reportedly found an injury on her head.

An autopsy was conducted on the body at a government-run Gandhi Hospital.

Police officers said they will take up the investigation into the murder after establishing identity of the victim.

The investigators were also trying to find out if the woman was sexually assaulted before the murder.

Since nothing was found on the body which could help in the identification, the police were relying entirely on the tattoo on her hand. By releasing the tattoo picture, they have appealed to people to inform the police station if they know anything about the woman.
