Doorbell video footage landed a man in jail for breaching a restraining order.
Callum Bermingham, 32, breached the order by calling and then visiting his ex-partner’s home on 15 January.
Bermingham, of Acer Road, Peterborough, was arrested and refused to be interviewed but later pleaded guilty to two counts of harassment – breach of a restraining order.
Police had been given doorbell footage showing him knocking at the door.
Bermingham was jailed for 32 weeks at Peterborough Crown Court and also handed a five-year restraining order, but walked free due to time served on remand.
Detective Constable Robert Giffen, who investigated, said: “We take breaches of restraining orders very seriously and will do all we can to bring offenders before the courts.”
