A 36-year-old man arrested in connection with the unsolved murder of American artist Margaret Muller has been released on bail.

Ms Muller was stabbed to death while jogging in Victoria Park six years ago.

The man was taken to a Cambridgeshire police station and has been bailed to return in April pending further enquiries.

A second man, aged 46, who was arrested last Tuesday (February 4) on suspicion of assisting an offender, has also been released on bail.

The pair are the eighth and ninth people to be arrested by officers investigating the attack.
