A 60-year-old woman was found dead in her Brooklyn apartment — after her ex-boyfriend, barricaded himself inside, police said Thursday.

Officers sent to conduct a wellness check on the woman arrived to discover the 62-year-old man barricaded in the home on East 5th Street near Ditmas Avenue in Kensington at around 8 p.m. on Wednesday, cops said.

Once cops got inside, they found the woman dead on the kitchen floor and the former beau in a back room with a cut on his chest, police said.

It is unclear how the woman died and whether she had any visible injuries. Her name was not immediately released, pending family notification.

The man was taken to Maimonides Medical Center.

Authorities could not immediately say whether the woman’s death was considered suspicious, but said the man is in police custody “pending the investigation.” 

The city medical examiner’s office will officially determine the woman’s cause of death.
