BROOKLYN - Police arrested a 15-year-old today in connection with Saturday’s Brownsville fire that injured his two siblings.

Investigators say the teen was playing with matches when the blaze started on the second floor of the apartment building at 373 Blake Ave.

His brother, 4-year-old Rolando Rich, and his 3-year-old sister Dasani were unconscious when they were rescued by firefighters and taken to Brookdale Hospital with burns and suffering from smoke inhalation.

He has been charged with assault, reckless endangerment and endangering the welfare of a child.
