Police are calling for information in relation to a series of incidents last week involving home-made explosives.
In the early hours on 25 and 26 January, there were reports of loud bangs in the areas of Pioneer Avenue, Kensington Street, Cowburn Road, and Hazelwood Road.
Minor property damage was caused to a bus shelter, letter box and window but no injuries were reported.
New Norfolk Police, Bridgewater CIB and the Bomb Response Group have conducted a number of searches in the New Norfolk area, and police have interviewed several youths who are being proceeded against for relevant offences.
Officers are confident that they have seized all relevant materials and have safely disposed of any remaining explosive devices.
