BROOKLYN, New York (PIX11) — Three men were wounded in three separate shootings across Brooklyn in the span of less than 10 hours Sunday, according to authorities.

In the most recent incident, a 35-year-old man was shot in the back near Malcolm X Boulevard and Fulton Street in Bedford-Stuyvesant around 11:20 p.m., police said. First responders brought the victim to an area hospital. He was expected to survive.

The victim is a security guard who spotted his vehicle that had been stolen and tried to get it back, but he ended up shot, police sources told PIX11 News. Police are searching for a group of men last seen running away from the scene.

Hours earlier, a 71-year-old man was shot in the chest inside his home on East 48th Street near Lenox Road in East Flatbush around 5:10 p.m., police said. The man was shot during an attempted robbery, police said.

Police said two women knocked and the victim’s door. The victim apparently recognized one of the women, so he let them in. At one point, the women allegedly asked the victim to loan them money. When the victim refused, one of the women shot him, police said.

First responders rushed that victim to an area hospital, where he was listed in critical condition. No arrests were immediately made.

The string of shootings began back in Bedford-Stuyvesant around 2 p.m. when a 31-year-old man was shot in the stomach inside an apartment building on Pulaski Street near Lewis Avenue, officials said. First responders brought that victim to an area hospital, authorities said, noting that he was expected to survive.
