Crocodiles taken from Sydney enclosure

Two crocodiles have been stolen from a mobile zoo in Sydney's south west.

Workers noticed Snap and Crackle were not in their George Crescent enclosure at Sandy Point around 5:30 pm on Friday afternoon.

Police say there were no signs of forced entry but are concerned for the reptiles - which are 80-to-100 cm long - because crocodiles are unlikely to survive outside of a controlled environment.
