BRIGANTINE, N.J. (CBS) – Authorities are investigating a blaze that swept through a multi-unit home in Atlantic County Friday morning.

Firefighters were called out to the 900 block of Brigantine Avenue in Brigantine just after 3:30 a.m. Firefighters were greeted with heavy fire and smoke billowing from the roof.
