Tension prevailed in Podanur in the city, when four crude bombs were hurled near a mosque and nearby houses in the early hours of today.

The people woke up after hearing a sound and noticed the remains of bombs, said to petrol-filled bottles connected with wicks, near the mosque on the outskirts of the city, police said.

The police, who rushed to the spot, found remains, like empty liquor bottles and wicks, of two more such bombs at the houses of one Meerankutty and Sulaiman, some 20m away from the Sunnath Jamaath Masjid.

A large number of police were deployed following growing tension.

The city is already caught in an uneasy calm after a couple of days of communal clashes, following the murder of a Hindu Munnani functionary, C Sasikumar on September 22. This incident created further panic.
