A MAN has been arrested under the Explosives Act after police and bomb disposal experts were sent to a house in Saltash.
Royal Navy bomb disposal experts were called to Parkesway after police discovered suspicious chemicals while executing a search warrant.
The property was searched by police officers who said they came across items and chemicals of concern.
Following investigation by Devonport-based Southern Dive Unit the items were not found to be dangerous.
Police said a man in his 30s, who cannot be named for legal reasons, has been arrested under the Explosives Act in connection with the incident.
Officers stressed the incident was not terrorism-related.
Devonport-based Southern Dive Unit bomb disposal experts were called to examine the items while police cordoned off Church Road and part of Parkesway.
The experts remained at the scene while the police continued to search the property.
A police spokesman said: "Following the execution of a search warrant at a property in Parkesway, Saltash this morning officers discovered some items and chemicals of concern.
"As a result EOD (explosive ordinance disposal) were requested and attended the scene, and following examination these items were not found to be dangerous.
"The area was cordoned off as a precaution and EOD remain at the scene whilst the search continues.
"A local man, aged in his thirties has been arrested in connection with the incident and remains in custody at Charles Cross Police Station awaiting interview."
They have been there since at least 10am this morning.
Witnesses reported two police vans in the area and a van with 'RN bomb disposal' on the side.
Residents were forbidden from entering their homes at the bottom end of Parkesway, where it meets with Church Road.
One elderly man had to take refuge in the local police station while the cordon was in place.
A neighbour in the street said: "The guy who has been arrested lives there with his mum and dad.
"You never get anything like this around here. It's really quiet."
Another man, who did not wish to be named, added: "I assumed there had been an accident when I saw the police had closed the road and set up a cordon. It's not often you see the bomb disposal van around here."
One witness who lives nearby said that activity seems to be surrounding a particular house.
A Ministry of Defence spokeswoman said: “The Southern Dive Unit have been sent to an address in Saltash to assist Devon and Cornwall Police.”
