Reward in Coton couple hammer attack robbery probe
A £5,000 reward has been offered by police investigating a "horrendous" attack on an elderly Cambridgeshire couple in their home.
A gang of four men subjected the couple, in their 70s, to a four-hour ordeal in Coton on 29 November.
The woman was hit with a hammer, and the man was repeatedly pricked with a brooch pin, police said, before the gang made off with valuable antiques.
CCTV of a man thought to be connected with the robbery has been released.
The incident took place in Madingley Road between 22:00 GMT and 02:20.
The woman's toe was broken after it was hit with a hammer and she also had 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".
A CCTV image of a man taken during a burglary in Landbeach in December 2013 has been released by police.
Det Insp Alan Page, said: "We believe the person in this image has information which will help our investigations into both incidents.
"The subsequent robbery was one of the most horrendous offences I have investigated in 20 years of policing."
A 35-year-old man from Cambridge was arrested on 27 December on suspicion of robbery. He was later released on bail until 29 January.
