The incident took place at about 9:30 p.m. ET in the 4400 block of Bellwood Drive.

The chemical reaction devices were then rendered safe by the bomb squad, according to authorities.
The devices did about $50 worth of damage, but no one was injured.
Police say multiple vehicles were seen leaving the area just prior to the explosions.
An investigation into the incident is ongoing.
