WHILE emergency services were on standby at Pembroke Castle to deal with an "unknown substance," they had a group of unexpected visitors.

Four ducklings wandered through a police cordon, attempting to make their way to the Castle Pond.

Sadly, the four baby ducks got lost among the hose reels on site being used by Mid and West Wales Fire and Rescue.

But help was at hand, as one of the firefighters spotted the ducks after they emerged from the underside of an engine.

The firefighter escorted the frightened youngsters under a hosereel and sent them on their way to the castle pond (video below).
