A £5,000 reward is being offered for information leading to the conviction of those responsible for the attempted murderer of an Oldbury man.
Albert Joseph, 71, was left fighting for his life after four men forced their way into his Titford Road property on Sunday, February 10.
He suffered cuts to his head, face and throat and was in hospital in a serious condition.
They also held a knife to his six-year-old son's throat during the robbery.
The robbers fled with jewellery, an iPhone and £700 cash in what police believe was a targeted attack.
Police previously arrested seven people on suspicion of attempted murder.
Men aged 35, 36, 38 and a 40-year-old woman were bailed to return for further questioning while three others were released under investigation as enquiries progress.
Anyone with information should call force CID on 101 quoting log 1629 10/2 or the independent charity Crimestoppers on 0800 555 111.
