A team of counter-terrorism officers and armed police have arrested a 22-year-old man in relation to the murder of a British soldier in Woolwich last week.

The man was apprehended by a group of five officers wearing balaclavas near Highbury Corner in north London around 2.45pm. No shots were fired during the arrest.

The officers took the man to a police station in south London, where he remains in custody on suspicion of conspiracy to murder.

Eyewitnesses told the Guardian that the officers arrived at the scene in a silver car and white van. One witness said: "The guy was on a push bike when the police came out of nowhere and wrestled him to the ground."

A Scotland yard spokesman said: "A 22-year-old man was arrested by officers from the MPS Counter-Terrorism Command investigating the murder of Lee Rigby. The man was arrested on suspicion of conspiracy to murder by detectives supported by specialist firearms officers.

"He has been taken to a south London police station where he remains in custody. He was arrested in St Paul's Road, in Highbury Grove, north London."

Today's arrest is the fourth made by officers in relation to the Woolwich murder over the bank holiday weekend.

On the evening of Saturday 25 May police armed with machine guns entered three separate residential properties in London, using a taser in one instance.

All three men arrested in the simultaneous evening raids were in their 20s.
