The needle of suspicion in the killing of Mukesh Panchal, whose decomposed body was recovered from the Chandola Lake three days after he went missing in a mob attack in the Shah Alam area, points towards six persons arrested in connection with the clash, police said in Ahmedabad.

Panchal (35), a resident of Lambha village near Ahmedabad, was riding pillion with one Ajay Shah on the latter's scooter when the duo was attacked by a rioting mob in the sensitive Shah Alam area on November 7.

Shah somehow managed to escape and reached the L G Hospital. He reported to the police that Panchal had gone missing.

Police recovered his scooter near an industrial unit at Narol Circle in the city outskirts the next day.

After an intense three-day search by the police, Panchal's body was recovered on Tuesday about 100 feet from the bank of the lake on the city outskirts.

Police spotted the body floating on the water. It was found to be in an 'extremely decomposed' state. Panchal's legs, neck and thighs were tied tightly with iron wires used in fencing. The killers had tied two heavy stones, one to Panchal's neck and another to the waist, to ensure that the body did not come out of the water.

A Forensic Science Laboratory Official said there were holes in Panchal's face as acid had been poured to conceal the identity.

Panchal's family members identified the body.

Sources said Panchal may have been dragged into a house and then killed. FSL officials have taken samples of blood from a room located in the lane leading to the lake for testing and comparing with that of Panchal's.
