I have been asked to share this, just in case anyone saw anything.

After leaving Crufts tonight my mum went back to car park North 5. Unfortunately she couldn't find her car and left her Grandson in charge of a large Hik9 dog bed by the mound in the middle. He left it for 1 minute and in that time someone stole all the shopping. Please share in case someone saw something. Our son is devastated as he thinks it is his fault. Please can you publicise as someone must have seen something.

have they checked with the carpark staff, security staff and nec staff incase someone thought the shopping had been forgotton and handed it in to someone?
If I came across stuff on the floor unattended that's what I would have done, taken it to a member of staff incase the owners came back looking for it.
