A father has been found guilty of murdering his son - after he slashed the baby's throat in a baker's shop.
Hassan suffered a fatal knife wound to the neck
Shahajan Kabir, 40, denied murdering 10-month-old Hassan Martin in Greggs bakery in Carlisle on 21 October 2003.
A jury at Carlisle Crown Court also found him guilty of wounding Hassan's mother Lorna Martin and grandmother Pauline Martin in the same incident.
He was given a life sentence with a recommendation he serve 12 years before being considered for parole.
Kabir, who was facing deportation back to Bangladesh, followed Hassan and the two women into Greggs where Miss Martin was ordering a cake for Hassan's first birthday.
The jury rejected an argument that Kabir was suffering from depression at being refused access to Hassan and that this had affected his state of mind.
Kabir will be deported from the UK after completing his sentence.
After the verdict, Hassan's aunt Zoe Muir said: "We took Mr Kabir into our home and our family and he betrayed us in the cruellest way imaginable.

"We are extremely grateful and give all our thanks to all those who left flowers and gifts outside Greggs, who signed the book of condolence and gave to the nominated charity.
"We also thank the witnesses who came forward to give evidence."
Earlier the court heard how Kabir had talked about dying only two hours before the incident.
The jury had been told how Kabir was "smiling" as he attacked his baby son in his pushchair.
Pauline Martin, who lived with her daughter and grandson, said Kabir entered the shop with a knife hidden in a plastic bag.
She said the injuries to her and the baby's mother came as a struggle began to free Hassan from Kabir.

Det Ch Insp Bill Whitehead of Cumbria Police, who led the murder inquiry, said: "Mr Kabir had gone through the full process of immigration appeals and was rejected.
"Matters relative to his removal from the country are something for the immigration service.
"However, I do not have any criticisms of anybody.
"It has been a very, very difficult case for many of my officers and there have been some mechanisms put in place to help them.
"But it has to be said that the many witnesses who came forward made my job a lot easier. There wasn't the wall of silence that people presume exists in serious cases.
"I think the people of Carlisle wanted to stand up and be counted."
