Greater Manchester Police said the pair were seen “acting suspiciously” on Chapel Street in Salford at around 2.30pm on Wednesday.
They were stopped in a vehicle in nearby Deansgate, which runs through a busy shopping and nightlife district near Manchester Arena, where an Isis-inspired bombing killed 22 victims in 2017.
“They remain in custody for questioning on suspicion of commission, preparation or instigation of acts of terrorism,“ a spokesperson said.
“A precautionary cordon is currently in place around the Range Rover on Deansgate after suspicious items were discovered in the car.
