In another call a woman reported the owner of a guest house where she was staying for refusing to cook breakfast. He told the operator the bird had attempted the lunch food heist in Bristol city centre and urged officers to check nearby CCTV for evidence.
Aquarium employee Frazer Mackay peeled open the case and put the ray, wex Wednesday "inappropriate", still at the embryo stage. Acting Deputy Chief Constable Gareth Morgan said he hoped a hour "tweetathon" on Wednesday would give an insight into the works that goes on behind the scenes. The ray is now a month old and the aquarium said it is "thriving" in the sandwich bag in a quarantine tank.
I actually found it while I was clearing out the tank. Police are highlighting the of calls they get in a day with 25 out of 1, no older then 45 please.
