The procedures to bring the animals are in the final stage, said an official.
The monkeys were brought here in exchange for two Hyaenas.
Revenue Minister K Rajan said the Central Zoo Authority has given permission to move a total of 479 birds and animals – 117 birds, 279 mammals and 43 reptiles – to the zoological park.
After being informed about the presence of the animal, the zoo staffers came and caught the female primate using a net.
The naming of the lions – a five-year-old male and six-year-old female- was done by Minister J Chinchurani.
The pair of hybrid lions are aged five and six years.
The VACB would begin the probe after registering the FIR as soon as the Forest Department gets the Government's nod to transfer the case.
Minister J Chinchu Rani said that vaccination for animals has started already.
422 animals died in the zoo in the past five years.
Following a preliminary investigation, the Forest Vigilance department has recommended suspending all staff involved in the incident.
