The family of a murder victim who was tied up and shot in the head during a warehouse raid have urged anyone harbouring the alleged killer to turn him in.

Tahir Zarif - who prosecutors claim shot Akhtar Javeed in the legs, throat, and mouth - is at the centre of an international manhunt after allegedly flying to Pakistan with his mother, five days after the February killing.

The jury during the six-week trial was shown distressing CCTV footage of Mr Javeed being gunned down at point-blank range as he tried to escape from his catering supplies firm in Birmingham.

The court was told that Mr Javeed was killed after being asked to take a masked gunman to a safe.

On Tuesday Zarif's business partner, Suraj Mistry, 25, was found not guilty of murder, but guilty of manslaughter, conspiracy to commit robbery and possession of a firearm with intent to cause fear of violence.

A second defendant Lemar Wali, 19, was found not guilty of murder and not guilty of manslaughter, but jurors convicted him of conspiracy to rob.

The raid was launched after sacked delivery driver, Sander Van Alten, 50, provided inside knowledge, including a plan of the warehouse drawn on the back of a water bill.

Van Alten admitted conspiracy to rob before the start of the trial.

In a plea for information on Zarif, Mr Javeed's daughter, Lilas Javeed said: "There is no real closure when it's murder.

"There have been three people brought to justice. It's three less criminals roaming the streets but of course it's very important for us that the other person is brought back."

The 30-year-old also called her father the "best dad you could ever wish for".

Speaking of the CCTV footage shown to the trial, Ms Javeed said: "I think the hardest bit was actually seeing the footage of what had gone on - to see your dad's last moments being as horrendous as they were.

"He was helpless and we feel like we couldn't help him."

Detective Chief Inspector Martin Slevin, of West Midlands Police also called for the public to come forward with information on Zarif: "This was a planned, callous, cold-blooded murder - there is no other way of describing it.

"The offenders planned this offence over a number of weeks and days - they brought firearms to the offence location, one fitted with a silencer.

"They brought cable ties with which to incapacitate all of the staff, and this was only made possible by the information provided by an inside man.

"We would urge anybody who has information where Tahir Zarif is currently living or being harboured to contact West Midlands Police, or Crimestoppers in confidence.

"If you're overseas, contact your embassy and pass that information on, so that we can attempt to bring him back to the UK to face trial for this offence."

Mistry, Wali and Van Alten will be sentenced on September 27.
