Detectives investigating the London Bridge terrorist attack have confirmed three men arrested in Ilford on Wednesday are still being held under terrorism legislation.

They confirmed that a 27-year-old man arrested on a street in Ilford and a 29-year-old man arrested at an address in Ilford - both arrested on suspicion of the preparation of terrorist acts - are now being held under the Terrorism Act 2000.

They were arrested at around 10pm on Wednesday, initally under the Police and Criminal Evidence Act.

As well as the above arrests, a 30-year-old man, arrested at an address in Ilford at approximately 01.30am on Wednesday, on suspicion of the preparation of terrorist acts, remains in custody under Terrorism Act legislation.

A 33-year-old man arrested on a street in Ilford on suspicion of possession with intent to supply controlled drugs at around the same time, and was yesterday further arrested on suspicion of firearms offences. He has since been bailed to a date in late June.

They have also obtained a warrant to prolong the detention of a 27-year-old man arrested under the Terrorism Act on Tuesday.

The warrant expires at 08.05am on Sunday.

Twelve others arrested in the early stages of the investigation were all released earlier this week without charge.
