Update at 1:40 p.m. — MCFRS has given the all-clear and officials are allowing people back into their businesses.

Original story: MCFRS and MCPD officials have evacuated the Shoppes of Bethesda strip mall on Hampden Lane after workers in the Montgomery County liquor store (4920 Hampden Lane) reported a strong chemical odor.

MCFRS officials believe the odor was brought into the liquor store through the HVAC system. Workers were on the roof with chemical products.

One person on the scene was feeling ill from the odor but did not want to go to the hospital.

Hampden Lane between Woodmont Avenue and Arlington Road is closed. MCFRS officials are running tests inside the liquor store.
