CHITTOOR: The police of Andhra Pradesh were placed on alert Monday following the receipt by the Commercial Taxes Department of a letter purportedly written by activists Al Ummah, a terror outfit based in Tamil Nadu.
Al Ummah was banned by the Tamil Nadu government after its involvement in the 1998 Coimbatore blasts. The Commercial Taxes Office (CTO) at Kattamanchi in Chittoor town received an envelope containing 10 letters bearing the name of Al Ummah.
In the letter, the outfit owned up responsibility for a bomb blast that took place at the district court complex in Chittoor town on April 7 while Chintu alias S Chandrasekhar, the prime accused in the murder of the town's mayor and her husband last year, was being taken to court. The letter did not threaten of any action either in Chitoor or elsewhere but bore an image of slain Al Qaeda chief Osama bin Laden.
The CTO Office immediately informed the Chittoor One Town Police, who in turn collected the letters from CTO.
Later, speaking to mediapersons, officials said: "In the letter purportedly written by Al Ummah, the group claimed responsibility for the bomb blast in the Chittoor court complex on April 7 in retaliation for the killing of two terrorists in Telangana earlier."
After the receipt of the letters, police have beefed up security in the town. They are not ruling out a prank by someone.
