A father was found guilty of murdering his ten-month old baby son at a shop in Cumbria.

Shahajan Kabir, 40, was convicted of slashing the throat of his son Hassan Martin at Greggs in Carlisle.

The jury at Carlisle Crown Court also found him guilty of unlawfully wounding Hassan's mother, Lorna Martin, 21, and grandmother, Pauline Martin, 40, in the same incident.

Kabir killed his baby son six weeks after being told he would be deported back to Bangladesh.

He was denied political asylum on September 10, 2003, and was due to be deported from the UK, where he had lived as an illegal immigrant since 1996.

But, on October 21, 2003, he was still in the country when he committed the murder.

Kabir had followed Hassan into Greggs Bakery in Carlisle where his mother, Lorna Martin, was ordering a cake for Hassan's first birthday.

He attacked Hassan, who was still strapped in his pushchair, and slit his throat from ear to ear with a 12inch knife.

As well as facing deportation at the time of the attack, Kabir was separated from Miss Martin, 21, and had limited contact with Hassan.

Kabir, whose parents, five sisters and brother still live in Bangladesh, came to Britain via Kuwait in 1996.

He had a six-month visa, but when it expired Kabir went to ground in Carlisle, working as a tandoori chef at takeaways in the city.

When he met Miss Martin in 1999 he asked if she would marry him and have his children.

She turned him down, but the pair became a couple in 2001 and in August that year Kabir moved in with Miss Martin and her mother, Pauline Martin, 40, at their Carlisle home.

He was arrested by chance on May 1, 2002 by Immigration Service officials when they raided the Indian Spice takeaway where he worked.

They were looking for someone else, but arrested Kabir and held him at the Immigration Removal Centre in Gosport, near Southampton in Hampshire.

Kabir again applied for political asylum and his application was supported by Miss Martin, who was now pregnant with Hassan.

On September 10, 2003, his final appeal to stay in the UK was dismissed and he faced deportation back to Bangladesh.

With his deportation date looming, Kabir tracked down Miss Martin and Hassan in Carlisle town centre on October 14, 2003, when he tried to kidnap his son.

One week later he killed Hassan.

Outside court, Miss Martin's sister, Zoe Muir, said, "Lorna and her family have found attending court over the last two weeks a very difficult and emotional experience.

"Hassan was a lovely little boy who always seemed to have a smile on his face for everyone.

"It has been difficult to come to terms with the fact that such an innocent child could have died in such a brutal way, that his life was cut short so suddenly and at such an early age."
