Authorities are questioning three men after pulling them from a submersible vessel in the East River in Brooklyn, N.Y., according to reports from ABC affiliate WABC.
The men were captured near the Brooklyn Cruise Terminal in downtown Brooklyn, near the massive cruise ship the Queen Mary 2, just after 11 a.m.
The intent of the three men being held by police remains unclear, but the initial indication is that it did not appear to be terror-related. They have not been identified by police and no charges have been filed.
The orblike vessel, with a circular hatch on the top for entering and exiting, remains moored in the East River in the Red Hook section of Brooklyn. It was equipped with oxygen tanks, WABC reported.
