MONTAUK - Police and the SPCA say they are searching for suspects in three different cases of animal cruelty on Long Island in the last month.

Suffolk County's SPCA is offering a $1,000 reward for information leading to the arrest of the person who stoned a seagull to death in Montauk over the weekend.

According to officials, a guest at the Royal Atlantic Hotel lured the bird with bread and then threw rocks at it Saturday. The stoning was captured on camera.

It is the third act of cruelty against wildlife in Suffolk in recent weeks. Last Friday, a swan was found shot with an arrow in Riverhead. Earlier this month, a turtle was discovered in Sag Harbor with a nail through its shell.

Cruelty against wild animals is a misdemeanor crime punishable with up to one year in jail.  SPCA investigators say each of the incidents was premeditated.

The SPCA held a news conference today asking anyone who witnessed these attacks to come forward.
