A
gunman opened fire on a police station in the Maryland suburbs of
Washington, D.C., on Sunday, killing one officer in what authorities
called an unprovoked attack before the assailant and a second suspect
were arrested.
The accused
gunman was wounded in the ensuing shootout with several officers outside
the station but was expected to survive, Prince George's County Police
Chief Henry Stawinski told reporters hours later.
Neither suspect was immediately identified.
The
police chief said he could offer no explanation for what might have
precipitated the attack on the District 3 police station, which lies
adjacent to county police headquarters in Landover, Maryland, about 8
miles (13 km) east ofWashington.
"It wasn't about anything,"
Stawinski told reporters at a news conference outside the hospital
where the slain undercover officer, Jacai Colson, 28, was declared dead.
Colson, a four-year veteran of the force, had been rushed to the
hospital by a fellow officer in the back of a squad car.
"This
man launched an attack on a police station and engaged several Prince
George's County police officers in a gunfight, to which they responded
heroically," Stawinski said.
He called the late-afternoon attack
unprovoked, adding: "My understanding is he opened fire on the first
officer he saw and then continued that conduct as officers became aware
of what was going on, and then several officers engaged him."
One
eyewitness was quoted in The Washington Post as saying she heard the
sound of what she thought were firecrackers outside, then looked out her
window to see a man dressed in black firing a handgun at the police
station.
Police
said the second suspect was under questioning Sunday night and no other
individuals were believed to have been involved in the incident.
According to the Post, authorities described the second suspect as the
gunman's brother.
