Officers seized equipment believed to have been used for unlicensed radio broadcasting during a raid at a property in Wellingborough.
Police officers teamed up with colleagues from OFCOM to jointly execute a search warrant last week, authorised by magistrates under the Wireless and Telegraphy Act 2006.
During the morning of Thursday, October 4, a search was carried out at a property in Abbey Road, Wellingborough, where unauthorised and unlicensed radio broadcasting was believed to be taking place.
A radio transmitter and other broadcasting equipment were seized from the address as evidence of the offences.
