A SENIOR member of Humberside Police staff has been arrested on suspicion of assault and stalking.
Retired Chief Superintendent Colin Andrews, pictured, who now works as business manager for the force's criminal justice unit, was held after a woman and man were allegedly assaulted.
The experienced detective has been released on bail and suspended from his job while officers investigate.
It is believed Mr Andrews, 57, spent a night in the cells at a police station in Hull after the arrest on Tuesday.
During his career as a police officer, which began in 1975, he was involved in cases on the south bank, including the investigation into the death of skydiver Stephen Hilder, at Hibaldstow airfield, in July, 2003.
He headed up the force's operations branch and oversaw the investigation into the murder of nine-year-old Aaron Smith, who died in a fire started by his stepfather, David Burtonshaw, in 2005.
He was also responsible for reopening the investigation into the murder of Hessle driving instructor Keith Slater, who was stabbed on his doorstep in 1988. It led to the conviction of Martin Brown for his murder in 2007.
Mr Andrews retired as a police officer last year, but took on a civilian role within the criminal justice unit.
He continues to work as a senior investigating officer and has recently concluded a two-and-a-half year investigation into historic sexual abuse at the St William's children's home, in Market Weighton.
A spokesman for the force said: "Police were called at 7.09pm on Tuesday reporting an alleged assault of a 38-year-old man and a 40-year-old woman outside an address in Park Grove, Hull.
"Police resources were deployed and a 57-year-old Hull man was arrested at 7.50pm on the same evening in west Hull.
"The 57-year-old man was arrested on suspicion of two counts of assault by beating and one of stalking. He has been subsequently released on police bail pending further inquiries.
"He is a police member of staff and has been suspended, pending further investigation."
Both assault by beating and stalking carry maximum prison sentences of six months and can only be tried by magistrates.
