Over The Fence is the 1128th episode of The Bill.
Sgt. Cryer and P.C. Loxton go to the scene of a disturbance between neighbours. They manage to calm the situation down, but when Loxton recognises one of the neighbours from when he arrested him once a few years ago for burglary, and then finds the box for an expensive computer which he suspects is stolen, he and Cryer find themselves drawn into another dispute between the two couples. They're both found to be in possession of computer equipment stolen during a ram raid robbery of a factory, and each one claims to have bought it from the other.
