A 79-year-old man died more than a month after he was brutally beaten just steps from his apartment building in downtown Brooklyn, police said.

The septuagenarian appeared to swing his cane before the assailant socked him in the side of the head, knocking him to the ground, video of the incident shows.

The attacker continued pummeling him in the face, before taking off, according to the video.

79-year-old Angel Diaz was taken to Methodist Hospital, where he was initially listed in stable condition.

He was later transferred to Bellevue Hospital, where he was pronounced dead on Thursday, according to police.

The assailant remains at large as of Wednesday.
