Seal pups which were at the centre of an appeal for used towels to be donated to a Norfolk wildlife centre have been released into the wild.
The RSPCA's East Winch Wildlife Centre needed the towels to help care for sick and injured seals.
Centre manager Alison Charles said the King's Lynn centre had subsequently been overwhelmed with towels, which are used to handle and keep pups warm.
Four pups were released into the River Nene in Lincolnshire on Tuesday.
Mrs Charles said another batch of pups was scheduled to be returned to the wild in about three weeks.
