Update from Bev Farmer.
'On checking the crates at cargo no cable ties where on them to secure the crate door this is standard practise to use the cable ties. The crates are pre moulded around the rim of the door for them has a secondary backup if the lock on the door failed. Once the crates are secured in the hold they are covered by netting but when they went to remove the crates the crate door was open and no Crystal . There is no sign of damage to the crate that she had tried to break out she is a relaxed traveller. The locking mechanism was only turned half way not in the full lock position . At the moment an investigation is under away to establish why no cable ties on the crate CCTV footage is being checked at Heathrow so we wait to hear for their report ., The other issue the dogs were sent without their collars they were taped to the top of the crate . To try and remove a dog in such a risky situation just coming off a flight and no collar is dangerous.
