UPPER MARLBORO, Md. (AP) — Two men accused of setting off a “bottle bomb” at a Maryland movie theater have been indicted by a grand jury.

Prince George’s County prosecutors said Tuesday that 20-year-old Manuel Joyner-Bell and 23-year-old Michael Hollingsworth were indicted on charges including possession of a destructive device, assault, and reckless endangerment

Both were arrested after a May explosion at the Magic Johnson Theater in Largo. Authorities say Joyner-Bell confessed to setting off six bottle bombs at five theaters in the Washington area this spring. Officials say sealed soda bottles combining acid and a base inside were detonated, panicking moviegoers and leading to evacuations but causing no serious injuries.

Authorities say Hollingsworth is believed to have been Joyner-Bell’s accomplice in the incidents.

Both are being held without bond and also face charges in Virginia.
