Amin Asmin Tariq, who is among the 24 persons arrested over the alleged terror plot to blow up US-bound planes, is said to be an employee of a private Indian air carrier.
The airline declined to comment when asked if Tariq, 23, was their employee.
A western media report said Tariq, a British national, is from east London and a security worker in Heathrow airport and was arrested at Walthamstow dog track after a car chase.
When contacted, London Metropolitan Police said they will not give out details about the arrested persons unless they are charged.
