Police are investigating a suspicious package and a collection of plastic bottles that were found at Wilmington's Frawley Stadium on Wednesday morning, according to multiple reports.
Wilmington Police arrived at the Minor League ballpark at 11:15 a.m. after reports of several explosions inside the stadium. Police believe an unknown suspect threw several plastic bottles filled with a mysterious chemical over the fence and onto the right field grass. The bottles eventually depressurized but did not cause any damage to the field.
Police said the ballpark, the Carolina League home to the Class A Advanced Blue Rocks, was unoccupied at the time of the incident. A package or bag was also found in the north parking lot of the stadium and was also being looked at by the Explosive Ordnance Disposal Unit. Police said it contained "suspicious items," according to newsworks.org.
The nearby area has not been evacuated, but the parking lot has been closed to traffic.
Wilmington general manager Chris Kemple told the website that the police isn't overly concerned with the items.
"It sounds like it's just pranksters and an isolated incident," Kemple said.
The evidence has been given to the Fire Marshal's Office. The Blue Rocks, a Royals affiliate, are on the road until June 3.
