One of the men accused in the hacking death of a British soldier has reportedly been attacked in prison.
Soldier Lee Rigby, 25, was killed on May 22 on a London street near his army barracks. The grisly murder shocked Britain and much of the world.
Sources told Sky News that one of the suspects, 28-year-old Michael Adebolajo of Essex, was attacked in London’s Belmarsh prison.
Adebolajo apparently lost his two front teeth in the Wednesday attack, the BBC reported.
Metropolitan Police said in a statement Thursday that the incident is under investigation.
"We can confirm that an allegation of assault was passed to the MPs on the 17th July by Belmarsh prison,” the statement read.
Adebolajo and Michael Adebowale, 22, of London, both alleged Islamic extremists, have been charged with murder and possession of a firearm with intent to cause violence.
Adebolajo is also charged with the attempted murder of two police officers, Sky News reported. They will stand trial on Nov. 18.
Last Friday, British Prime Minister David Cameron joined thousands of people at Rigby’s funeral.
Rigby's family and mourners were greeted with applause by members of the public lining the streets outside Bury Parish Church in northwest England, where soldiers from Rigby's Royal Regiment of Fusiliers had maintained an honor guard overnight.
The service was private, in keeping with the family's wishes, but broadcast on loudspeakers to well-wishers packing the street outside the church.
Rigby's commanding officer, Lt. Col. Jim Taylor, described the soldier -- who is also a drummer -- as "extremely popular" and "truly charismatic," telling mourners that he loved to perform.
Rigby's death caused a spike in racial tensions in Britain due to the apparent involvement of religious extremists. Police reported an increase in attacks against Muslim mosques and community centers in the subsequent weeks.
