BROOKLYN - Police are investigating a possible hate crime in Borough Park after swastikas were spotted on five different buildings in a four-block radius, including a synagogue and a public school. Police say the buildings were marred with swastikas overnight. The community has the largest population of Holocaust survivors and relatives in New York State. Councilman David Greenfield (D-44) is offering a $1,000 reward for information leading to an arrest.
