A watchdog has told a police force it should investigate its handling of the initial Victoria Hall murder inquiry between 1999 and 2001.
The Independent Office for Police Conduct (IOPC) said it had received a referral from Suffolk Police of complaints related to its investigation into the murder of the 17-year-old in 1999.
