MANCHESTER, N.H. (AP) — Police say a fatal shooting in Manchester, New Hampshire, has set off a search for the gunman.

The city's SWAT team blocked off several blocks and eventually surrounded a home where the gunman was believed to be barricaded inside late Friday afternoon.

WMUR-TV reports that the shooting happened around 11 a.m. and that the victim died at a hospital.

Officers were looking for a white man seen fleeing from the scene.

A secure campus policy was put into place at Manchester Central High School. No one was being allowed on or off campus.
