Stolen bikes

My flatmate's bike was stolen on Friday night from Corn Street in Bristol. It was a silver BSA courier fixed gear conversion with chrome wheels.
Unfortunately, I don't have a photo of the bike itself but this the closest I could find on the internet:

Any help would be appreciated. Cheers

Hello, I saw this post on gumtree and had some suspicions about it so I searched the forum for any reports of this bike and yours is the only one I found. They look really similar but it's up to you to judge whether this is your friend's bike. All the best.
