Four men were stabbed in central London's Covent Garden on Wednesday, and police arrested a woman in connection with the attack, which they described as a suspected mental health incident. The Metropolitan Police said the stabbings happened around lunchtime in the popular shopping and entertainment district, which is frequently crowded with tourists. The victims' conditions were not immediately disclosed. A witness, Arjan Gjorga, who works at the Rock and Sole Plaice fish restaurant on nearby Endell Street, said the woman was known to workers on the street. He described her as a homeless person who regularly walks around the area asking for help and visits a church at the top of the street. Police have not named the woman or said whether she has been charged.
