Five powerful country-made bombs have been found inside a movie hall in the city, police said on Wednesday.
An abandoned cloth bag containing the bombs was found on a seat on Wednesday evening by a woman, who alerted an employee of Sakthi Shivam theatre, they said.
"The bombs looked like those used for killing wild animals, police said, adding hunters usually smear some food items on such bombs to lure animals so that they explode when bitten.
Such bombs explode when slight pressure is applied on them. Had the woman sat on it without noticing it, the same would have exploded, they said.
"It is not known whether bag has been left deliberately or someone brought it and forgot to take it away," they added.
