Almost a dozen people were injured Friday afternoon after a nasty five-car collision on the Prospect Expressway. The crash occurred just past 2 pm on Feb. 26 when, authorities say, a Mercedes Benz traveling westbound near Fourth Avenue struck two cars that were involved in a minor accident, pinning at least one man and prompting a pileup that also included an MTA bus. At least one man had to be cut out of his vehicle, police said, and a 23-year-old woman remains in critical condition following the incident. Traffic was backed up for several exits afterward.
