Police will today begin a post-mortem examination on a body that was recovered from the Humber Estuary yesterday (Wednesday, March 20) afternoon.
Calendar sources described a "large police presence" close to Grimsby Docks yesterday afternoon, where the RNLI brought the body ashore.
The body had been recovered from the water close to Spurn Point at around 3:30pm.
The investigation into the circumstances of its death has been passed to the coroner in Hull.
Formal identification is expected to take place following the post-mortem.
Police have given no further details, saying it is "too early for any identification or confirmation of gender" to be made.
A spokesperson said: "Formal identification is expected to take place following the post-mortem, until which time we are not in a position to confirm as to who we believe it may be."
