A Northeast Fire Department Association Bomb Squad used a water cannon to disarm what officials from the Bureau of Alcohol, Tobacco, Firearms and Explosives described as "a serious bomb that could have caused some serious harm."
The package was discovered on the front doorstep of a home in the 1000 block of Dogwood Court near Colleyville Middle School.
Just after 11 a.m., police called in the bomb squad and evacuated several nearby homes. The bomb squad used a water cannon to neutralize the explosive device. The water cannon shoots a large amount of water into the device and renders it safe, immediately.
Agents from The Bureau of Alcohol, Tobacco, Firearms and Explosives said the bomb could have left the person who opened it with serious burns, had it functioned properly.
ATF agents reassembled the remaining parts of the explosive device, which will then be sent to an ATF lab in San Fransisco for analysis.
Police have no suspects and no one was injured.
