Las Vegas police said they captured a chimpanzee that escaped from her owners for the second time in a month. Police said CJ the chimpanzee escaped from her enclosure at a home in the northwestern part of the city Saturday afternoon and officers responded around 4:50 p.m. to set up a containment area, the Las Vegas Sun reported Monday. Officers were able to use tranquilizer darts provided by North Las Vegas Animal Control to capture the primate around 5:30 p.m. near her home. Police said CJ and her mate previously escaped July 12 and police were forced to shoot and kill the mate before CJ was recaptured. The chimp was returned to her owners, who improved the security on her enclosure. Police said CJ will not be returned to her home this time.
