A UK terror suspect who is facing multiple robbery with violence charges will know his fate in September 9.

Jermaine Grant, 31, was put on his defense by Nairobi magistrate, Kiarie Waweru, yesterday but he chose not to defend himself against five counts of robbery with violence accusations against him.

He is also facing charges of attacking a police post in Wajir four years ago and escaping from police custody.

Lawyer Mbugua Mureithi told court yesterday that Grant had decided to remain silent in his defense, but the prosecution had not adduced enough evidence to prove that he had escaped from lawful custody.

Grant, who is on world's terror watch list is said to have involvement with al-Shabaab, which has been responsible for numerous bombings in Mombasa, Mogadishu and northern Somali.

The Briton, whose family comes from Newham, East London, is also facing terrorism charges in a Mombasa court where he is accused of planning a bomb attack in the coastal town and possessing explosive materials.

He was charged in December 2011 alongside three Kenyans, Fouad Abubakar, Manswab Warda and Frank Ngala, with terrorism related charges after they were found with materials used in making bombs

The prosecution said they were found with batteries, wires, ammonium nitrate, nacetone and hydrogen peroxide.

Before the magistrate court in Nairobi, the police said Grant with the help of a gang, stole four guns, bullets and a police car in Wajir five years ago. An officer was injured during the attack.

The prosecution called police officers to testify against him and showed the court the guns he allegedly stole.

The court heard that he was arrested near the Somali border on May 31, 2008 at Dadajabula AP post but was freed an hour later by an armed gang suspected to be militants belonging to the al-Shabaab.

In March, it emerged that his accomplice who allegedly plotted the 7/7 London attack was planning a violent raid to break Grant out of a prison.

Police said they believed Muslim-convert Samantha Lewthwaite, 29, from Aylesbury masterminded a scheme to break Grant out of custody before a court appearance.

Prosecutors said two men, who were arrested with grenades and bullet proof vests, later confessed to the mission to free Grant.

As a result, the trial, was moved to 'safe' court at the Shimo la Tewa prison.
