Man arrested for shoving West Village diner cook into plate glass window

An unhinged man flew into a dyspeptic rage Saturday morning when he was asked to leave a West Village diner, shoving a 77-year-old cook into a plate glass window and then running off to Washington Square Park — where three brave employees found and held him until cops arrived, workers told The Post.

The disturbing incident unfolded around 9:45 a.m. in the Washington Square Diner on 6th Avenue and West 4th Street when the man — who police identified as Gregory Conwell, 27, of Red Hook — began bothering customers, workers said. Workers said Conwell has been in the diner multiple times before, annoying patrons and even pretending to be one of the waiters. On Saturday, they said, he came in to use the restroom.
