Update at 6:30 p.m.: Investigators have determined that the substances found in the apartment were cleaning supplies and chemicals such as acetone, police spokesman Lt. Kip Malcolm told ARLnow.com. The substances were held in “weird containers,” for reasons unknown. Hazmat teams have cleared the scene.

Earlier: Police and the Arlington County hazmat team are investigating a possible drug lab found in a Crystal City apartment.

Arlington County Police, Virginia State Police and the hazmat team were called to the Crystal Square Apartments (1515 Jefferson Davis Highway) this afternoon after the Arlington County Sheriff’s Office found “suspicious items” and substances in an apartment during an eviction. The items include laboratory equipment like respirators, scales and beakers, according to ACPD spokesman Lt. Kip Malcolm.

The hazmat team is performing tests on the items to determine what they are and if they’re hazardous. While the equipment may be for some sort of drug lab, it’s not suspected to be a meth lab, which would have prompted evacuations. So far, the building has not been evacuated, Malcolm said.

There have been no reports of any health problems in the apartment building nor of any arrests made by police. Police have closed a portion of 15th Street S. near the scene as the investigation continues.
