A man who was arrested after two explosive devices were found in a north London flat on Wednesday has been released on police bail, as detectives said they do not believe he has links to any terrorist organisation.

Counter-terror police have continued to investigate the find in an empty flat in the Brent area. But they said they believed the area was safe and that there was no ongoing risk to the public on Thursday evening.

The 48-year-old man, whom officers have not identified, had been arrested earlier in the day on suspicion of an offence related to explosives and was further arrested for possession of class A and class B drugs after being taken to a south London police station. He was released hours later and bailed until late December, Scotland Yard said.

Officers did not specify what conditions, if any, were placed on him. They said initial tests indicated that the two items were improvised explosive devices (IEDs), though further forensic examination was ongoing on Thursday evening.

Officers were called to reports of two suspicious items in a flat that was unoccupied and being refurbished shortly after 9.30am on Wednesday. They evacuated the block and closed nearby roads as a precaution and later made the IEDs safe.
