Beast Coast, the NYC rap supergroup featuring Flatbush Zombies, The Underachievers, Joey Bada$$ and other Pro Era members, are on a summer tour through the end of the month. They were scheduled to play Sterling Heights, MI venue Michigan Lottery Amphitheater on Sunday (8/11), but that show was cancelled when threats of a shooting were called into area police departments, Macomb Daily reports. Auburn Hills and Sterling Heights police departments each received a phone call threatening violence at the concert; after the second, promoter 313 Presents announced its cancellation, two hours before the show was to start.

Sterling Heights Police Chief Dale Dwojakowski late Sunday confirmed the department's front desk received a phoned-in bomb threat that came in on the department's non-emergency line.

"There was a reference to gun violence at (Sunday's) show," the chief said. "We related that information to the Macomb County Sheriff's Office, as they do the policing for the county park, which is located in Sterling Heights. I'm told they met with the production company and the decision was made to cancel it."

Although extra security was going to be provided by the sheriff's office, Wickersham said either the band's management or the promoters made the decision to cancel the show.

"In today's world, it's better to be safe than sorry," he said.

An investigation into the source of the calls will be made, Sheriff Anthony Wickersham said.
