Dave, a diver, holds a reel of diving thread, similar to what he used during the November 2019 siege of the Hong Kong Polytechnic University (PolyU) when he dived into the submerged sewage system from Victoria Harbour to help scout a subterranean escape route from the campus, as he participates in a recent diving expedition in the waters off Hong Kong, China, in this undated image.
