A vandal believed to be responsible for at least 16 incidents of anti-gay graffiti—much of it directed at Barack Obama—has been caught on video tagging a doorway, police said Thursday. The suspect, who police are still seeking to identify, can be clearly seen in surveillance footage writing the word F-G on the door of an Astoria building on 18th Street and 27th Avenue.

Police say that the tag matches the suspect's handwriting and profile. Earlier this week, two different garages in the area were spray-painted with the words "Obama f-ggot." Similar graffiti was found at the 18th Street location location last month as well. And in March, an Astoria office shared by two lawmakers was defaced with the anti-Obama message on three separate occasions.

The man can be seen in security camera footage during one of those March outings, though his face is mostly obscured in that video. Police have since described the suspect as 6 foot tall and about 200 pounds, and say he was last seen wearing a black jacket with a hoodie, black pants, and dark boots.

According to 114th Precinct commander Deputy Inspector Peter Fortune, the NYPD's Hate Crime Task Force is currently investigating the spree, and looking at surveillance footage from other buildings in the area.

Anyone with information in regards to this incident is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782).
