Police arrested a man Tuesday and were seeking a second in connection to the thefts of propane tanks in Northeast Philadelphia earlier this month.

The men were not identified, though they were described as collectors of scrap metal. Counterterrorism officials had been alarmed by the thefts.

Investigators found some of the tanks and two suspect vehicles at a lot in the 2600 block of Wheatsheaf Lane. Thieves took 34 propane tanks and welding equipment from three locations. - Robert Moran
