Police are appealing to the public to contact them if they know the whereabouts of 23-year-old Khan, from Birmingham, who is wanted in connection with the extensive torture of a young woman and other more recent attacks.
Crimestoppers is supporting the investigation by offering a reward of up to £10,000 for information that they exclusively receive which leads to the arrest of Khan.
The reward is available for three months and is due to expire on 15 June, 2024.
As a result of her ordeal, the young woman was left with a broken nose, severe swelling to the eyes and significant damage to her mental health.
Khan is wanted in connection with these offences and two other more recent separate attacks, where he allegedly hit one person over the head with a hammer and slashed another with a machete.
It is believed Khan is a class A drug dealer who administers punishment to those who pay him late.
The advice is not to approach Khan, but to contact police, or Crimestoppers if you wish to stay anonymous.
Khan’s girlfriend, 36-year-old Imaan Coley, has been found guilty for the torture of the woman and is awaiting sentencing.
Detective Inspector Jim Bailey said: “Khan is known to be a dangerous man and it is vital that he is arrested as soon as possible.
“There is a real risk that others could come to harm. If you know where he is, I would urge you to do the right thing and contact us.”
