Two Carroll County teenagers have been charged in connection with a series of explosive devices placed inside mailboxes last week in South Carroll.

Deputy State Fire Marshals said the arrests were made after a weeklong investigation into the use of improvised destructive devices to damage property.

Blayne Cianci, 19, of Finksburg was taken into custody at his home on Monday afternoon without incident. A 16-year-old male juvenile, of Sykesville, has also been charged, fire marshals said.

The arrests stem from an early morning incident on Sept. 3 when six "destructive devices" were placed inside five mailboxes and a propane gas grille in Sykesville and Woodbine areas.

Fire marshals said the devices were created by using illegal fireworks materials which were ignited and discharged — destroying the mailboxes and the grille. The fireworks components were modified consumer fireworks, which even unmodified, are illegal for sale and use in Maryland, according to the fire marshals.

The State Fire Marshal's Office said both Cianci and the juvenile have been charged with six counts of manufacturing and possession of a destructive device, six counts of malicious destruction of property, six counts of discharging fireworks without a permit, and six counts of possession of fireworks without a permit.

The juvenile has been released to his guardian pending further action by the Department of Juvenile Services. Ciance was being held at the Carroll County Sheriff's Department Detention Center as of Monday evening, pending a bond hearing.
