Italian police are hunting two men who executed a Chinese immigrant and his baby daughter on a Rome street.
Zhou Zheng, 31, and his family were targeted by two men on a motorcycle shortly after he closed his coffee bar and money transfer business in the south-east of the city last Thursday.
The men - wearing helmets - demanded he hand over 5,000 euros (£4,125) in takings that they believed he was carrying.
When he refused, one of the men fired three shots, hitting Mr Zheng in the stomach and his six-month-old daughter Joy in the head.
Mr Zheng's wife Lia, 26, was then stabbed and remains in hospital in a serious condition.
When police arrived at the scene they found Mr Zheng had 3,000 euros (£2,475) on his person.
In a sign of how the attack has shocked the nation, Italian President Giorgio Napolitano yesterday visited Lia in hospital.
According to Mr Napolitano, his visit was both a gesture to Mrs Zheng and one of solidarity to the Chinese population in Italy.
He said: 'She is destroyed by sorrow for the horrible murder of her daughter and her husband.'
The president also vowed to catch the killers.
He added: 'It is something that we owe to ourselves. It is a duty that we owe to Italy, and it is also a duty that we owe to the Chinese people and the Chinese community.'
Detectives suspect the killings were carried out by two young migrants from North Africa.
Mrs Zheng has revealed how the family's assailants shouted at her husband shortly before he was murdered.
She said: 'They screamed at my husband saying, "We'll kill you like a dog."'
