LONDON: A Muslim man in London who was released without charge after running over a knife attacker has said it was “his duty to act.”

The 26-year-old Chechen, known as Abraham, works as an electrician and was on his way to a job in London on Jan. 24.

While driving through the neighborhood of Maida Vale, he spotted a man stabbing a woman in the street three times in the chest.

Witnesses tried to stop the attack by Leon McCaskie on his ex-wife Yasmin Chkaifi, but to no avail. Both McCaskie and Chkaifi died after the incident.
