A man arrested after a protest march in London over cartoons of the prophet Muhammad has been fined for failing to notify police about the demo.

Former UK head of radical Islamic group al-Muhajiroun Anjem Choudary, 39, was found guilty of holding an unauthorised public demonstration.

Choudary, of Ilford, Essex, was charged after the rally outside the Danish embassy in February.

He was fined ?500 and told to pay ?300 in costs by Bow Street magistrates.

Placards

Hundreds protested about publication of the cartoons in Danish newspapers in two separate demonstrations on 3 and 4 February and charges were later brought.

The court was told Choudary telephoned police ahead of the demonstration and said he was a lawyer for a group wanting to gather outside the embassy.

According to prosecutors, on the day of the protest he called officers again to say there would now be a march from the mosque in Regent's Park to the embassy.

But for such a march to be legal Choudary should have given six days' written notice as required under the 1986 Public Order Act.

Some of the placards waved outside the Danish Embassy during the protest are alleged to have incited violence.

Last month the charges against another of those arrested were dropped due to insufficient evidence.

Omar Zaheer, 26, from Southall, west London had been accused of racially aggravated disorderly behaviour.

Outcry

Four other men still face trial in relation to the protests on 3 February.

Abdul Muhid, 23, of east London, is facing two counts of soliciting to murder.

Umran Javed, 26, from Birmingham, Mizanur Rahman, 22, of north London and Abdul Rahman Saleem, 31, of east London, each face one count of stirring up racial hatred.

Javed and Mizahir Rahman are also facing one count of soliciting to murder.

Protests were held by Muslims across the world after the satirical cartoons first appeared in a Danish newspaper.

Among the images which sparked outcry was one of Muhammad with a bomb-shaped turban on his head.

Newspapers in Spain, Italy, Germany and France were among those to reprint the material.
