A warning about the dangers of walking thin ice has been issued after a parent was seen carrying a toddler across a frozen lake.

The man could be seen stepping onto the lake with the youngster in his arms without any consideration that they may fall through.

His actions have been described as "crazy" by the Coastguard, which released a picture of the incident and warned of the dangers of stepping on ice.

Two teenagers have previously drowned at the lake, which is up to 50ft deep in places.
