Drug-filled tennis balls thrown into Suffolk prison
A man has been arrested after tennis balls filled with drugs were thrown over the wall into a prison.
A man was seen attempting to throw the balls into HMP Highpoint, near Haverhill in Suffolk on Friday.
Police tweeted to say one of the balls, containing suspected controlled drugs, was retrieved by a police dog named Harry, with other balls being found by a prison dog.
They said a suspect ran away but a man was arrested later.
Police dogs are trained using tennis balls - but they are usually given as a treat in a game of fetch to reward the dogs for their good work.
