Concerned passer-by appeals for information after little dog Henry plunges into frozen Roundhay Park lake

The incident took place yesterday (Sunday) when the popular beauty-spot was partly frozen as temperatures plummeted.

The concerned witness, who wishes to remain anonymous, wrote on Facebook about how a 'little dog called Henry' ran onto the ice before it broke and fell in.

Bystanders rushed to the aid of poor Henry in a desperate bid to get him our of the freezing water, according to the spectator, with one 'brave lad' stripping off with the intention of entering the water to retrieve Henry, but was persuaded not to.

"After 20 minutes of combined efforts got him out. Well done to all involved."

He added: "If anyone knows Henry’s owner, we would like to know that he is OK.
