Animal welfare officers are appealing for information regarding three small kittens which were dumped in a doorway in Boston on Tuesday.
The incident happened at about 11.30am, when the kittens were abandoned in Hatter Lane, which runs off the High Street, down the side of Boston Sausage.
CCTV footage has captured a group walking away from the May Fair towards the town bridge and RSPCA officers would like to trace them as they believe they may have information about the incident.
The group is comprised of an adult female, a young girl, and an older girl or young woman.
RSPCA and police officers have released a CCTV still of the group.
Anyone with information should call the RSPCA on 0300 1234 999.
