Chickens and duck decapitated at Victorian school

Police have released images of two males they want to speak to about the beheading of three chickens and a duck at a school in Melbourne's southwest.

The headless birds were found in their enclosures by students and staff of a Point Cook school the morning after the attack earlier this month.

The offenders broke into the enclosure at around 9pm on October 1 and killed the birds, police say.

Images have been released of two males in hooded jumpers who police believe may be able to help with investigations and are urging people who may have information to call Crime Stoppers on 1300 333 000.
