Now accused of hurling abuse at soldiers

Mohammed Abdul Kahar, 23, and Abul Koyair, 20, allegedly screamed "We hope you die in Iraq" and spat at Welsh Guardsmen on duty outside Wellington Barracks, central London, according to The Sun newspaper.

A Metropolitan Police spokeswoman said: "We are investigating an allegation of harassment outside Wellington Barracks at 10:00 pm (local time) on August 1.

"There have been no arrests."

Kahar and Koyair were arrested at their home in Forest Gate, east London, in a June 2 raid that was prompted by what police said at the time was "credible" intelligence that chemical weapons were being manufactured there.

Despite an extensive, week-long search nothing was found, prompting a backlash from local people and some Muslim community leaders.

The brothers -- who are of Bangladeshi origin -- were also released after days of questioning.

Kahar was shot in the shoulder during the raid, which involved about 250 officers. A police watchdog report last week concluded the shooting was an accident.

On the same day the report came out, Kahar was arrested on suspicion of child pornography offences. He denies any wrongdoing.

The brothers are currently staying at the "four-star deluxe" Crowne Plaza Hotel, near Queen Elizabeth II's Buckingham Palace residence and the Met's headquarters at New Scotland Yard while their home is being repaired.

Wellington Barracks is opposite Buckingham Palace.
