Fifth arrest in Coton hammer attack robbery probe
A fifth man has been arrested in connection with a violent attack on an elderly couple at their home.
Four men subjected the couple, in their 70s, to a four-hour ordeal in Coton, Cambridgeshire, last November.
The woman was struck with a hammer, and the man repeatedly pricked with a brooch pin, police said, before the gang made off with valuable antiques.
A 34-year-old from Cambridge was arrested on Friday and later released on bail, police said.
Another 28-year-old man from Cambridge was arrested on Thursday and was also bailed.
Three men previously detained over the attack - a 33-year-old from Peterborough, a 35 year-old from Merton, and a 42 year-old from Cambridge - were interviewed again by officers last week and released on bail.
The incident took place in Madingley Road between 22:00 GMT and 02:20 on 29 November.
The woman's toe was broken after it was hit with a hammer and she also sustained a black eye, police said.
The offenders wore white boiler suits and balaclavas.
Items taken included a pair of jade storks and what police described as a "solid silver Aztec artefact".
Det Insp Alan Page, from Cambridgeshire Police, said the raid was a "vicious and calculated attack that left its victims in fear for their lives".
A £5,000 reward is being offered for information leading to a successful conviction.
