A 19-year-old soldier has been arrested on suspicion of terrorism offences after a nail bomb was found at a house.
Officers raided the Army based in Paderborn, Germany, following the discovery of the suspicious device at a terraced house Mellor Street, Eccles, on November 28.
He was flown to the UK and questioned by detectives in Greater Manchester before he was released on bail until January pending further inquiries.
A spokesman for Greater Manchester Police said: "Police have arrested a man in connection with the investigation into a suspicious device found in Salford last Thursday.
"A 19-year-old man was last night arrested on suspicion of Section 57 of the Terrorism Act. He has now been bailed until January.
"Shortly before 1.30pm on Thursday November 28 a warrant was executed at an address on Mellor Street in Patricroft.
"A 20-year-old man was arrested on suspicion of possession of abusive images and was bailed pending further inquiries.
"During a search of the property on Mellor Street, a suspicious device was found. A cordon was put in place and a number of residents were evacuated as a precautionary measure. Specialist officers assessed the device and were later able to confirm it was no longer a threat to the community."
Last week, bomb disposal officers were called to safely remove the device as residents were evacuated to a local school.
Police arrested a 20-year-old man on suspicion of possession of abusive images and "several items of literature which could be viewed by some as potentially inflammatory" - reported to be extreme right-wing leaflets.
