A 27-year-old man from Dundas has been arrested after a bus compound in Dundas was robbed twice in three days of dozens of bus batteries, according to Hamilton police.

The break-ins happened on Aug. 17 and Aug. 20, police said. The first time, the suspect stole 15 bus batteries — lugging the 40-pound batteries right out of the buses themselves. The second time, 11 batteries were swiped.

The man has been charged with two counts each of breaking and entering, trafficking and possession of stolen property under $5,000.

“They are slightly larger than a car battery,” Const. Asuf Khokhar told CBC News previously. “They are being used for the purpose of scrapping them.”

Each battery costs about $150 at retail, but you’d only get about $15 to $20 per battery used.
