The police department Saturday afternoon issued a "public safety message" after four suspected heroin overdoses in a period of ten hours.

Authorities said three of the four apparent overdoses in Johnson City were fatal.

Detectives were in the preliminary stages of investigating the incidents and specific details involving the overdoses were still being determined.

Because of the sudden rash of deaths tied to possible overdoses, the police believe there is a "bad batch" of heroin out on the streets.

In the alert, officials warned "anyone who may be using heroin to be aware of the potential increased risk of overdose."

The police department urged people to be aware of the situation and to call 911 right away if they become aware of anyone experiencing an overdose.
