Police said no injuries were reported, though unspecified damage was reported at each location
In the first two instances, police said in a statement, a device was placed outside and then detonated.
All the attacks were in Northwest Washington.
Police described "suspects" in singular and plural form, though they didn't say how many people might be involved.📷
"It appears the suspect targeted commercial establishments and it does not appear the suspect was targeting any members of the public," police said in their statement.
In at least one of the three incidents, security video captured a vehicle that police associated with an attacker.
It was described as a champagne-colored or gold Acura TL, with a screen capture showing it as a four-door.
Anyone with information on the suspects or the vehicle was asked to call authorities.
