Washington, D.C., police are looking for a suspect or suspects who they believe set off two explosive devices and threw a Molotov cocktail outside three local businesses on Sunday.

The incidents all happened within 15 minutes early Sunday morning, the Metropolitan Police Department said in a news release. No one was injured in the suspected attacks, but three buildings were damaged. 

The first attack happened at approximately 4:30 a.m., when the suspect detonated an explosive device on the sidewalk outside the ATM at the Truist Bank located in the 2300 block of Washington Place, Northeast, authorities said. Police said the suspect sped away in a vehicle after the device went off, causing damage to the bank.

Six minutes later, police said, the suspect detonated a second explosive device on the sidewalk in front of the doors at the Nike Store located in the 700 block of H Street, Northeast, and again fled the scene in a vehicle. That location was also damaged by the explosion.

"The establishments were closed at the time of the offenses. There were no reported injuries as a result of these offenses."
