Description: BBC NEWS MAY 16, 2012. Two female giraffes have died after a zoo in the central Polish city of Lodz was raided by vandals.
One died of a heart attack just hours after the break-in, while the other was found dead on Monday after stress exacerbated a medical condition, officials said.
The zoo is looking for a companion for the remaining male giraffe.
Authorities are investigating the break-in, in which vandals threw debris into the animal enclosures.
Zoo director Ryszard Topola said that the three giraffes, from the endangered Rothschild giraffe subspecies, had been kept together as companions, and that the hope had been that one of the females might produce offspring.
He said three-year-old Suri was found dead early Sunday, with a post-mortem indicating that it died of stress and a heart attack.
Six-year-old Hana, who had been receiving treatment for parasites, died early on Monday, but the stress contributed to the death, Mr Topola said.
During the raid, unidentified hooligans threw benches and bins into animal runs, including one near the giraffe enclosure.
