BRIDGEPORT - Animal experts in southwestern Connecticut are calling for tougher laws and regulations after an incident in Ohio, where dozens of dangerous wild animals were freed by their owner and later killed by police.

Beardsley Zoo has some of the same wild animals that were involved in the incident, but Connecticut zoos and preserves have to be permitted and inspected on a regular basis.

Connecticut has tougher laws since Travis the chimpanzee attacked his owner's friend in Feb. 2009. The attack sparked tougher regulations in Connecticut, making it illegal to keep many wild animals as pets.

Jim Knox of Connecticut's Beardsly Zoo, says "While those laws keep something like the tragedy in Ohio from happening here, with no national standards, nothing prevents it from happening again in other parts of the country."
