New York Police Department is investigating sexual assault allegations against magician David Blaine.
Chief of Detectives Dermot Shea told reporters Blaine is under investigation but declined to discuss any details, including whether police had sought to interview him.
Mr Shea was responding to a report by the Daily Beast website that the NYPD had taken statements from two women accusing Blaine of sexual assault.
Citing unnamed sources, the report said one of the alleged victims claims she was attacked by Blaine in his Manhattan apartment in 1998.
The Daily Beast had previously reported that a former model alleged Blaine raped her in London in 2004, an allegation he denied.
Scotland Yard detectives later declined to take further action after investigating her claim, the website said.
Blaine, 45, is known for stunts like being buried underground for seven days without food or water in New York in 1999. He also stayed in a plexiglass case suspended 30ft above the Thames River in London for more than 40 days in 2003.
According to his website, he is to begin a tour of the UK and Ireland in June.
The NYPD said it “takes sexual assault and rape cases extremely seriously, and urges anyone who has been a victim to file a report so we can perform a comprehensive investigation, and offer support and services to survivors”.
