Justin Bieber greets three special fans in New York

Pop star JUSTIN BIEBER took time out from his busy schedule on Wednesday (20Jun12) to greet three female fans, who lost their police officer father in the line of duty last year (11).

New York Police Department Officer Peter Figoski was gunned down in Brooklyn while interrupting a home invasion on 12 December (11), leaving behind four young daughters, Christine, Caitlyn, Caroline, and Corrine.

Bieber made sure to put a smile on their faces by setting up a meet-and-greet with the starstruck fans ahead of his TV taping for U.S. program The Late Show with David Letterman.

Teenager Caroline was unfortunately unable to attend but the Baby hitmaker posed for pictures and chatted with her sisters outside Letterman's Ed Sullivan Theater home.
