Three men have been injured, one seriously, when what is believed to be a firebomb was thrown in their faces in a Bradford kebab house.

Detectives believe the attack at the Oasis takeaway in Morley Street was carried out in revenge following an argument between staff and some customers early yesterday.

Two men were today being quizzed by detectives about the attack.

The men, aged 20 and 21, were arrested on suspicion of arson with intent to endanger life following the incident early yesterday.

The other two remained in a stable condition at BRI last night.

A West Yorkshire Police spokesman said: “We know there was an argument at the takeaway which took place shortly before the fire and we would particularly appeal to anyone who was there at the time who could assist officers further in their investigations.”

Detectives in Bradford South are scrutinising CCTV footage from nearby businesses in the hunt for the attacker who struck at 1.25am.

The exact nature of the firebomb has yet to be established. One businessman, who runs a furniture store called the Trading Post, a short distance up Morley Street, said the owner of the takeaway was an Iranian man in his 50s who had operated the business in different outlets in the street for about 30 years.

The businessman, who did not want to be named, said yesterday: “All we’ve heard from the police is that there was an altercation then a firebomb. The owner is an absolutely superb fella and so is his family. He also owns some other properties round here.

“I came here this morning a bit earlier than normal and I rushed across to see if anyone had been injured but the police wouldn’t say. Nobody lives there.”

Asim Maqsood, who works at Universal Express travel agency next door to the takeaway, said: “The police are looking at our CCTV. I know the owner, he’s a brilliant guy. As far as I know he is away at the moment.”

The front of the takeaway was sealed off with police tape and was being guarded by a lone Police Community Support Officer yesterday lunchtime. A first floor window was wide open in the four-storey stone building.

Scene of crimes officers later carried out forensic tests inside the takeaway, which sells Mediterranean cuisine including kebabs and burgers.

The travel agency next door was where Police Constable Sharon Beshenivsky was murdered in 2005 when she was shot dead by armed robbers.

Detectives have urged anyone with information about the arson attack to contact the incident room at Trafalgar House police station on (01274) 376100 or Crimestoppers in confidence on 0800 555 111.
