A group of men and a child were spotted shooting swans and girls with a catapult.
Wiltshire Police is appealing for witnesses to the incident at a fishing lake in Swindon on Wednesday 25 August to come forward.
Officers investigating the incident say it happened at Plaum’s Pit lake, off Cheney Manor Road, at around 4pm.
