UK plane diverted after 'family row'

British police have arrested two men on a Pakistan International Airlines plane after fighter jets were scrambled to escort it to a London airport following an "incident".

Police said the men were detained on suspicion of endangering an aircraft after the plane, which was carrying 300 passengers from the Pakistani city of Lahore to Manchester in northwest England, was diverted to Stansted airport outside London on Friday.

"Two men have been arrested on suspicion of endangerment of an aircraft," police in Essex said in a statement.

"They are aged 30 and 41 and are being taken to a police station for interview by detectives."

The incident was not believed to be terrorism-related. An airline source told Agence France-Presse the incident had stemmed from a family row on board.

"There was a family of eight to 10 people on the plane and they were quarrelling among each other," the PIA source said.

"When PIA staff approached them and asked them to calm down, they told them to go away otherwise they would blow up the plane.

"PIA staff became scared and they raised the alarm to avoid any untoward situation."

A spokesman for the Ministry of Defence said that Typhoon jets had been launched from a Royal Air Force base after the incident was signalled by the plane's crew, shortly before the plane was due to land in Manchester at 1230 GMT.

"Typhoon aircraft from RAF Coningsby have been launched to investigate an incident involving an aircraft in UK airspace," the MoD spokesman said.

After the plane landed, the MoD spokesman said the incident was now a police matter and "our involvement is over".

Typhoon planes can be scrambled if the pilot or crew of a passenger aircraft sends out a passenger signal, he added.

"The purpose of going up is to investigate what the situation is," he said.

"Often when a Quick Reaction Alert aircraft is launched the details are not known, but it is known that a signal has been sent."

The incident came just hours after a British Airways plane was forced to make an emergency landing at Heathrow Airport with smoke billowing from one of its engines.

Heathrow was temporarily forced to close both its runways while emergency crews put out a fire on the Oslo-bound Airbus A319, causing heavy disruption at one of the world's busiest airports.

A British Airways spokesman said the incident was "a purely technical issue".
