**A man has been arrested after being “disruptive” on a flight from Amsterdam to Detroit - two days after a failed attack on board the same flight.**The pilot of Northwest Airlines Flight 253 requested emergency assistance as it landed on Sunday. The man, reportedly Nigerian, is in custody.
It came a day after a Nigerian man was charged with attempting to destroy a plane on a flight on 25 December.
President Obama ordered a review of air security following the first incident.
The BBC’s Andy Gallacher at Detroit Metropolitan Airport said the situation was unfolding and it was unclear what had happened on Sunday’s flight.
There was possibly more than one passenger involved, he added.
All 255 passengers were taken off the plane safely, and the plane was taken to a remote part of the airport for searching.
US media reports said the man was Nigerian and had locked himself in the plane’s bathroom.
Airport alertness
US President Barack Obama was told about the latest incident during his holiday in Hawaii.
The White House said in a statement: “The president stressed the importance of maintaining heightened security measures for all air travel.”
The US and international airports were already on alert after the 25 December failed attack, in which Umar Farouk Abdulmutallab allegedly attempted to detonate an explosive device.
Fellow passengers reported seeing flames coming from Mr Abdulmutallab’s lap.
The FBI said he had explosives on his body. He is due to appear in court on Monday.
