8:28 a.m. NYC Transit has an alert about service along the F line, due to a police investigation: "Jamaica-bound F trains are running on the D line between the Coney Island-Stillwell Avenue Station and the Broadway-Lafayette Station. Select Inwood-bound A trains are running on the F line between the Jay Street-Borough Hall Station and the West 4th Street-Washington Square Station. There is no G train service between the Bedford Avenue-Nostrand Avenue Station and the Church Avenue Station in both directions. Please expect delays in A, F and G train service." We are hearing that someone was struck by a train at 7th Avenue.

Update, 9:06 a.m.: The MTA is now saying, "Following an earlier incident A, F and G train service had resumed with residual delays." Still, a reader snapped this shot outside the Bergen Street station:
