Partizan Belgrade hooligan group's leader Ljubomir Markovic who once featured on "Real Football Factories" has been shot dead as hundreds of the Serbian side's fans descend on Manchester for the ​Europa League clash against the ​Red Devils.

Markovic, 37, was killed in the Serbian capital Belgrade as he was standing in the street, with the incident captured on CCTV cameras.

In footage seen by ​The Mirror, Markovic - who was allegedly the leader of the 'Alcatraz' gang of Partizan hooligans - and a group of his friends can be seen standing in front of a small local football stadium when a hooded man walks up to them.

The hooded man pulls out a pistol and opens fire on Markovic who sprints away. The gunman runs after him and the Partizan hooligan can be seen dropping to the ground.

Local media have reported that six shots were fired in total, with the final bullet hitting Markovic's head and killing him. Reports also state the killer fled the scene in a black BMW X5 with licence plates from the western Siberian city of Sabac.

The report also claims that a police investigation was launched and reports state Markovic himself was armed at the time of the attack but did not have time to use the weapon.

Markovic appeared in the Bravo documentary 'The Real Football Factories International', starring Danny Dyer.

He was earlier sentenced to 30 years in prison for the organised assault and murder of French football fan Bruce Taton in 2009, but his sentence was reduced to 15 years and he was released from prison earlier this year.
