LONDON, England (CNN) — Three men have been arrested in connection with the July 7, 2005, bomb attacks on the London transport network, British police said in a statement.

Two men, aged 23 and 30, were arrested at Manchester airport in northern England shortly before 1 p.m. GMT on Thursday as they were due to catch a flight to Pakistan, New Scotland Yard said.

A third man, aged 26, was arrested hours later at a house in Leeds. Police were searching five addresses in the Leeds area, the statement said.

“The three men were arrested on suspicion of the commission, preparation, or instigation of acts of terrorism under the Terrorism Act 2000,” it read.

Pakistan. It just keeps coming up.
