Four of the migrants cut loose without bail after allegedly ganging up on two NYPD cops near Times Square may be on the run, The Post has learned.

Cops believe the group hopped on a bus bound for California on Wednesday after giving phony names to a church-affiliated nonprofit group that helps migrants get rides out of the city, according to law enforcement sources.

Four migrants were charged with assault on a police officer and obstruction immediately after the shocking, caught-on-video attack Saturday in Midtown: Darwin Andres Gomez, 19, Kelvin Servita Arocha, 19, Wilson Juarez, 21, and Yorman Reveron, 24.

All were released without monetary bail, though Reveron, who had prior arrests on his rap sheet, was put on supervised release.
