A man who stabbed a young father to death has been filmed partying with prison hooch and singing to explicit rap lyrics in a sickening jail video. Dashem Tesfamichael, 30, is seen in the 50-second clip captured on a banned mobile phone as he dances outside his cell  with other inmates at Coldingley prison in Surrey. He clutches a glass of the homemade illegal brew in the clip, which also shows a stash of drink bottles, biscuits and crisps on a window ledge, before it was shared with friends on WhatsApp. Scroll down for video . Dashem Tesfamichael, 30, who was jailed for stabbing a young father, has been filmed partying behind bars . He was caught on camera drinking illegal alcohol and dancing to explicit rap music with other inmates at Coldingley prison in Surrey . Prison officers reportedly turned a blind eye to the partying, which happened in the run-up to Christmas in December last year. Tesfamichael was jailed for life with a minimum of 13 years after he used a broken champagne bottle to stab Olu Olagbaju, 26, in Shadan's nightclub in the City of London in December 2006. The music producer collapsed and died after the attack, where witnesses described seeing the young father being held with his arms behind his back before he was stabbed in the chest. Eritrean-born Tesfamichael, then 23 and living in Camden, north London, made his getaway in a Mercedes before fleeing to Italy and then Miami, U.S., before he was extradited back to Britain. The 50-second video clip was captured on a banned mobile phone and shared with friends on WhatsApp . Eritrean-born Tesfamichael will spend a minimum of 13 years behind bars for the stabbing of Olu Olagbaju, 26 . Mr Olagbaju was looking forward to the birth of his second child with fiancee Terri Jacob, who he already had a daughter with, when he was killed. The Ministry of Justice launched an internal investigation at the Category C prison, which houses 500 inmates, and dealt with those involved. A spokesperson from the Prison Service said: 'All identified prisoners have faced disciplinary action. This type of behaviour will not be tolerated.' Tesfamichael wears a grey vest as he dances around the prison with another inmate, who wears sunglasses . The footage also shows a stash of drinks bottles, crisps and biscuits being stored on a window ledge . The video has outraged members of the public after it was shared on social media. Vikki Heywood, wrote on Facebook: 'I think it's disgusting the stuff they can get up to in prison these days. I've seen other ones of take aways and stuff like that. 'They are there to be punished not rewarded. If they have it soo cosy they will never learn from there's mistakes [sic].' Richard Jones added: 'What's more shameless is that it's the authorities allowing the "party" to take place.'  Others described it as 'shocking' and 'disgraceful'.

Prison officers at Coldingley prison in Surrey reportedly turned a blind eye to the partying, which happened in the run up to Christmas in December last year . Prison inmates use the yeast food spread to make illegal hooch dubbed 'Marmite Mule' behind bars . Prisoners are infamous for brewing illicit alcohol while they're behind bars with the DIY concoctions carrying a variety of names from 'pruno' to 'hooch'. But it is perhaps surprising to learn how inmates are able to make the beverages on such a limited amount of resources. In 2009 it was reported that Marmite had been banned from Dartmoor prison in Devon because inmates were using it to make super strength hooch. Dubbed 'Martmite Mule', prisoners added it to fruit, vegetables, bread and water, with the yeast in the food spread triggering the fermenting process of turning the sugars in the fruit into alcohol. The brew is then left over two weeks in old soft drink bottles or plastic bags before it is strained with a T-shirt or sock to remove the remains of the fruit and veg. It was also reportedly being used at privately-run Addiewell Prison in Scotland. Pruno, or prison wine, is renowned for being made by inmates because it can be produced with the limited selection of equipment and ingredients available to them. It is usually made using a variation of apples, oranges, fruit cocktail, candy, ketchup, sugar, milk, and possibly other ingredients, including crumbled bread. Again, the use of a plastic bag, hot running water and a sock are needed during the fermentation process. The longer the concoction is left the stronger it will be with the alcohol volume ranging from 2 per cent to 14 per cent.
