Robin stuck in Tesco superstore!!

There is a robin that has been stuck in the 24 hour Tesco store in Llansamlet (Swansea) for the last few days.  Apparently they have contacted the RSPB but they were told that they weren't allowed to do anything until Spring.   Is this true???   The poor thing is desperately singing his heart out while looking out of the window..

Surely they can do something to get him out?   Although there may be plenty of food in the supermarket, there won't be any fresh water for it to drink.  It will die in there!  Someone must be able to do something???
