I'm so sorry to hear of Patrick going missing, I do hope he's found safe and well.
I've instructed our staff to help look out for Patrick as well as placing a large image of Patrick and the contact information on our information sign opposite The London Bridge Station to help in the search.
We're always very happy to try and help the local community and if we can be of any further help please let me know. and I so hope he is found safe and well.
You've probably thought of this but it may be worth contacting the nuns on St George's Road and asking them to distribute his picture through their clients. They run a mens hostel on a nightly basis, someone may have seen him.
