Video from the Museum of Modern Art shows the moment a man leaped over a reception desk and stabbed two employees as they tried to flee Saturday.

The video released by New York City police shows man police identified as 60-year-old Gary Cabana entering the museum lobby through a revolving door then climbing onto the desk and jumping over it as a man carrying what appears to be a walkie-talkie looks too scared to stop him.
