A father aged 76 was beaten unconscious as he slept in his bed by raiders who forced his daughter to jump from the window of a neighbouring bedroom.
The pensioner was set upon by thugs who ripped a gold ring from his finger after inflicting what police described as an 'appalling amount of violence' in his Wolverhampton home.
His daughter, 51, leapt 15ft from a first floor window as the attackers moved in to her room. Moments earlier, she had been punched in the face and fell to the floor. Thinking she was unconscious, the raiders left her. She was left with minor injuries from the fall and was today recovering in hospital. Her father has also been released from hospital.
Detectives were today hunting two men seen running from the house in Beckminster Road, Penn, at around 1.45am on Wednesday.
The ring, which is the only item stolen, has three tiers of diamonds and officers want to hear from anyone who has been offered a similar item.
They also want to hear from anyone who saw the two men running away from the house in the Penn area of Wolverhampton towards the direction of Coalway Road.
One of the men was 5ft and dressed in dark clothing, wearing a white head covering or hood and carrying a torch.
The other was described as 5ft 10in and was wearing dark clothing and a face covering.
Dc Gary Thompson, of Wolverhampton CID, said: "This must have been absolutely terrifying for the victims, who were subjected to an utterly appalling amount of violence. It's completely incomprehensible as to why someone would want to knowingly beat a 76-year-old man in his own bed.
"Thankfully, burglaries involving such violence are extremely rare and most offenders will strike when the house is empty. The two men responsible for this crime are clearly very dangerous and we need to get them off the streets as quickly as possible.
"We're following several lines of enquiry at the moment and have carried out extensive house-to-house enquiries but if there's anyone out there who we haven't yet spoken to and who feels they may be able to assist us, I would urge them to come forward.
"Were you out in the early hours of yesterday morning and saw men matching these descriptions acting suspiciously either before or after the time of the burglary? Have you been offered a gold ring with three tiers of diamonds in the last 24 hours?
"You may know the people who committed this offence but are unaware of the level of violence they used on two completely innocent and vulnerable victims do the right thing and call us or Crimestoppers anonymously."
Anyone with any information should contact Wolverhampton CID on 101 or Crimestoppers anonymously on 0800 555 111.
