Workers sickened; jail on lockdown

Authorities said a western Pennsylvania jail is on lockdown after almost a dozen employees became ill from an unknown substance.

Allegheny County officials said nine corrections officers and two medical personnel have been sickened since about 10 p.m. Sunday by some kind of odor or substance at the Allegheny County Jail.

County spokeswoman Amie Downs said all employees were taken to a hospital for evaluation and have since been released.

Officials said the jail will be locked down until further notice. State corrections officials said earlier that the cause of similar symptoms that prompted lockdowns at a number of facilities is believed to have been a clear, odorless chemical known as synthetic marijuana.
