(Updated at 12:45 p.m.) Bicycle thefts in Arlington are at an all-time high, according to the Arlington County Police Department.

A total of 67 bikes were stolen in July, but police say they’ve been working “aggressively” to reduce the number of thefts. At least six suspects were recently arrested in connection with bicycle thefts, and one pleaded guilty to nine felony counts.

According to police department statistics, from June 1 to Aug. 5, a total of 126 bikes were stolen for a total property loss of nearly $100,000.

The most common time for bike thefts was between 10:00 a.m. and 4:00 p.m., Wednesday through Friday. Trek was the most commonly-stolen bike brand, while the Clarendon area was the “hottest area for stolen bikes.”

Police are asking residents to take steps to make sure their bike is safe. From an ACPD press release:
