Police continue to investigate the “deafening’’ explosion that rocked Chelsea Saturday night, lamenting the lack of video evidence pointing to potential suspects.

“Right now there’s not much in the way of witnesses or video,” police sources told The Post of the blast, which injured 29 people, blew out scores of windows and forced the evacuation of at least two nearby buildings.
