Washington, Dec 15 (ANI): Leona Lewis’ attacker has pleaded guilty to assaulting the star at a book signing in London and been ordered to remain in hospital under Britain’s Mental Health Act.

Peter Kowalczyk, 29, who suffers from mental health disorder schizophrenia, appeared at London’s City of Westminster Magistrates Court to answer a charge of common assault, in relation to the incident which took place in October (09).

According to court documents, the pop star was left with redness and swelling to the face, and whiplash symptoms after being punched by Kowalczyk, reports Contactmusic.

A witness statement from Lewis says, “I feel completely devastated by this attack. Now I am very frightened about going out in public and I don’t know where the next attack will come from and if this will be more serious than what has just happened.”

District Judge Howard Riddle has ordered Kowalczyk to remain in hospital for an indeterminate period.

The judge told Kowalczyk: “This is what happens when you don’t take your medication. A woman is now devastated.” (ANI)
