Blackpool Zoo has said it is "absolutely delighted" that four of the five monkeys stolen from their enclosures have been found safe and well but saddened that the baby was not among them.
Two female cotton-top tamarins and two male emperor tamarins were returned to the zoo after they were found abandoned in Bradford overnight.
Charlotte Pennie, head of primates at the zoo, said: "We are extremely relieved that four of the monkeys have been found safe and well, although we are also saddened that the baby cotton-top Tamarin has not been found."
The zoo joined Lancashire Police in thanking the public help with the search, while officers appealed for more help in their ongoing investigation into Tuesday's planned theft.
This is a terribly tragic incident where a little girl has sadly lost her fight for life and I am determined to find out exactly what has happened to her and how she has come to acquire injuries so serious that they have proven fatal.
I personally encourage anyone who may have any information about little Kasey and the days leading up to her death to come forward to help us in what has now developed into a murder investigation.
