BROTHERS who plotted and carried out a vicious attack against the manager of a Tottenham mobile phone shop were jailed today.

Quamar, 30, and Umar Abid, left Sandeep Dattani for dead when they went to his West Ham home to steal the keys to the 02 shop in Tottenham Hale retail park.

When Mr Dattani tried to protect himself, Quamar, of The Bye Way, Harrow Weald, plunged a screwdriver into his chest with such ferocity it lacerated his heart, Inner London Crown Court.

During the trial, Quamar denied using a screwdriver and said the injury was caused by a set of keys.

He lost 1.5 litres of blood and was left fighting for his life as he underwent open heart surgery at the Royal London Hospital.

After attacking Mr Dattani, the pair raced over to the 02 shop less than half an hour later, but were unable to get through the second door and had to abandon their scheme.

Judge Charles Tilling, sentencing, said: "This was a carefully planned robbery. The manager of that mobile phone was attacked outside his home in order to obtain the keys to his shop.

When he resisted he was stabbed with something. Whatever it was, he was stabbed so severely that his heart was actually lacerated. He is lucky to be alive. You are lucky that you did not face a murder charge. All this in order to obtain some mobile phones to pay off a debt."

Umar, 25, of Woodlands Drive, Harrow Weald, had worked with Mr Dattani for 18 months at the time of the attack on October 15, 2009.

He had been sacked on the same day his brother joined the team after just one day working together.

Quamar received an 8-year sentence for wounding with intent to cause harm, four years for robbery and two for burglary, to run concurrently.

His younger brother, Umar, who was part of the plot but did not inflict the near-fatal blow, has been ordered to serve four years for robbery, and 18 months for burglary.

Sandeep Dattani and his wife were at the south London court to hear the verdict and smiled with relief when they hears the judge's decision.

Mr Dattani has since returned to work but is still recovering from the venomous attack. He said he was pleased with Judge Tilling's sentencing.

Detective Sergeant Copley, of Stratford robbery squad, said: "I think it was a fair verdict considering the offence. Mr Dattani could have died."

He added: "He had to have major open heart surgery, and is still trying to recover from that. He still has to undergo heart exercises."
