A man accused of assaulting pop star Leona Lewis is not fit to attend court, a judge was told on Monday.
Peter Kowalczyk, 29, was charged with striking the Bleeding Love singer during a book signing.
A hearing at City of Westminster Magistrates' Court heard he has been sectioned under the Mental Health Act and is being examined by psychiatrists.
After a short hearing of legal argument, District Judge Daphne Wickham adjourned the case until November 23 at the same court.
Kowalczyk did not appear in the dock and remains in secure accommodation at Lambeth Hospital in south London.
Witnesses said Lewis was struck by a fan as she signed copies of her autobiography.
The 24-year-old had been signing autographs for about 90 minutes when a man lashed out, leaving her with bruising to the side of her head.
Rehearsals for her first major UK show are due to begin next week. She is due to play the Hackney Empire next month.
