An administrative error by the Home Office risks the extradition of a British 'hit squad' accused of murdering a businessman in Albania in a feud over £80,000.

The gang - including a young mother - allegedly flew to the seaside resort of Shengjin, and posed as tourists as they checked into a five-star hotel owned by their target, Ardian Nikulaj.

There they accepted free meals from their unsuspecting victim, chatted with his wife and played pool with his 13-year-old son as they allegedly monitored his movements before one gave the signal to strike, the victim's grieving family claim.

A fifth alleged gang member then walked into the hotel restaurant and shot Nikulaj six times at point-blank range with a Soviet-made semi-automatic pistol before fleeing.

Horrific CCTV footage captured the brutal murder in April last year, along with multiple earlier visits to the hotel by the Britons, who were allegedly seen filming the inside of the restaurant.
