Thiruvananthapuram: Over the past few days Kerala has been kept on tenterhooks by phone calls, some of them apparently emanating from Pakistan, about Kerala being the next target for terrorist attacks.

Most of these have been hoax calls, though each has disrupted life in one town or the other. There have also been media reports, quoting police sources, that explosives have been transported into the state, which has caused genuine concern among people.

But there have been no serious leads and even school children have apparently got into the act, calling up from public phones to make threatening calls about bombs being planted.

The latest bomb scare was at the local bus stand in Nadapuram near Kozhikode yesterday. Police searched the area thoroughly but did not find anything suspicious.

Taken into custody

One of the pranksters was taken into custody on Monday after he made a call to a news photographer based in Thiruvananthapuram.

Police said the schoolboy, named Tejas, from Kozhikode, was taken into custody and interrogated after the police got the number of the caller from the news photographer. Tejas reportedly confessed to police that he had done it only as a prank.

There have been several other hoax calls from different parts of the state. On Monday a hoax call came to the chief minister's office warning of a bomb threat to the Alappuzha station of the All India Radio.
