London Metropolitan Police announced that Zakaria Bulhan, the man suspected of killing US tourist Darlene Horton in a stabbing rampage in the British capital, has been charged with murder.
The Norwegian citizen, a 19-year old, is of Somali descent and moved to Britain at the age of five.
He was also charged with five counts of attempted murder, police said in a statement.
Police raided his home in Tooting, south London, on Thursday after he was arrested on suspicion of murder.
The police received numerous calls on Wednesday describing a "man attacking people with a knife" between Russell Square, Montague Street, Bloomsbury Square and Great Russell Street.
Bulhan was arrested at the scene after police stunned him with a Taser following the attack, near the Imperial Hotel and the British Museum.
