A second property in Cheltenham has been raided by police investigating the making of explosives in the town.
A garage and a van were today at the centre of the police investigation which saw forensic officers searching the address with sniffer dogs.
A 57-year-old man was arrested yesterday at his home on Brooklyn Road on suspicion of making the explosives, when the police executed a pre-planned search.
Gloucestershire Constabulary say that both operations are connected, although not terror related.
