Police arrest suspect in shootings of homeless in Washington, DC and New York

"Early this AM, law enforcement arrested the suspect in Washington, DC. He is currently being interviewed at our Homicide Branch," the Metropolitan Police Department wrote. It added more information will come but gave no other details.

Authorities had been searching for a lone gunman whom they said was linked by forensic evidence to the shooting of five homeless men in the two cities.

The shootings targeting homeless men began on March 3 when Washington's Metropolitan Police officers were alerted to sounds of gunshots on New York Avenue at about 4 a.m. The victim was taken to hospital for treatment of non-life threatening injuries.

On March 8, police in that city found another homeless man suffering from gunshot wounds. He was transported to a hospital for treatment of non-life threatening injuries.

The following day, police spotted a tent fire on New York Avenue and found a deceased homeless man inside. Further investigation determined that he had suffered multiple stab and gunshot wounds.

Three days later, a 38-year-old man was shot in the arm in New York City's lower Manhattan.

A short time later, police responded to an emergency call about a man suffering from gunshot wounds to the head and neck, and found the victim dead inside a sleeping bag on Lafayette Street.

Police said a sixth victim initially thought connected to the attacks had been ruled as an unrelated medical incident.

The violence comes amid a rise in violent crime in both cities and a spate of seemingly random attacks in New York City.
