Police in England arrested two men under the Terrorism Act, but it was unclear whether they were suspects in the recent incidents.
Sky News, citing unidentified sources, said the two men were arrested following two deliveries of gas canisters to an industrial park. Gas canisters were used in all three car bombing attempts in London and Glasgow.
The men were arrested at noon in an industrial park in Blackburn, 220 miles (350 kilometers) northwest of London, Lancashire Police said.
"They have been taken to a secure police station in Lancashire. At this time it is too early to confirm whether or not these arrests are linked to recent events in London and Glasgow," a police statement said.
