A 26-year-old Dutch national from a Somali family who has lived in the U.K. since the age of 9, Mohamud pleaded guilty.

CCTV images showed Mohamud raising a steak knife and walking behind an unsuspecting couple.

He screamed "Allahu Akbar!" and stabbed James Knox, 54, repeatedly. He then turned the knife on Knox's companion, Anna Charlton, 57, slashing her across the face.

Sgt. Lee Valentine, 31, was also stabbed in the shoulder while confronting Mohamud.
