A fresh appeal for witnesses to come forward has been launched by Thames Valley Police following the launch of a murder investigation in Aylesbury.

TVP's Major Crime Unit launched the investigation on Monday after a man died on the Grand Union Canal shortly after 12.20pm, near to Broughton in Aylesbury.

The next of kin of the victim continue to be closely supported by family liaison officers.

A 34-year-old man of no fixed abode has been arrested on suspicion of murder in connection with this investigation. He remains under arrest and in the custody of officers while receiving hospital treatment.

A 41-year-old woman from Birmingham was arrested on suspicion of assisting an offender and perverting the course of justice. She has been released on police bail until May 24.

Senior Investigating Officer, Detective Chief Inspector Andy Shearwood said: “Officers are continuing to investigate the circumstances of this murder investigation.
