Hyderabad, Jul 14 (IANS): Andhra Pradesh continues to be on high alert following Wednesday's serial bomb blasts in Mumbai.

State police chief Dinesh Reddy, after reviewing the security situation at a meeting with officials, told reporters Thursday that police were on high alert.

Hyderabad Police Commissioner A.K. Khan said a tight vigil was being maintained in the city in the wake of the Mumbai blasts.

"While there is no need for any panic and there is no specific threat to the city, people should remain alert," he said.

Khan revealed that police have taken precautionary anti-terrorist measures. Ten teams have been constituted to keep a tight vigil in the city.

He asked people to remain alert and inform police of any unclaimed objects or vehicles in public places. "Even if we receive 100 calls about unclaimed objects and one call helps in detecting explosives it will be good percentage," he said.

Police also plan to check people's alertness by keeping bag filled with dummy explosives in public place.

Hyderabad was a target of terrorists in 2007. Nine people were killed in a blast during Friday prayers at the Mecca Masjid May 18, while 43 people died in two near simultaneous blasts at an eatery and a park Aug 25 the same year.

India's financial and entertainment hub was Wednesday hit by three serial blasts that killed 17 people and injured 141.
