At least 10 people were sickened in Newark Monday after ingesting synthetic marijuana, police say.

Newark police said that the calls started to come in around 8:12 a.m.

No deaths have been reported.

This is not the first time Newark has had an influx of people sickened by the substance. Numerous people became sick last April after ingesting synthetic marijuana. Newark police made numerous arrests after an investigation into those incidents.

Police are asking for the public’s help identifying where the synthetic drug came from. Anyone with information about these incidents is urged to call the department's 24-hour Crime Stopper tip line at 1-877-695-8477.
