LONDON -- The mayor of the English city of Liverpool was arrested Friday over allegations of fraud in building and development contracts, local media said.

The Liverpool Echo reported that Joe Anderson was one of five men arrested by detectives as part of an ongoing investigation.

Merseyside Police said men aged 62, 33, 46, 25 and 72 had been arrested and were being questioned "in connection with offences of bribery and witness intimidation."
