Bats are indeed a bit famous for carrying rabies, I think I would have animal control relocate the little guy.
Edit: I'm not at all suggesting that this bat in particular has rabies, or that people should be afraid of bats. What you should be afraid of is rabies, because that's fucking terrifying. Due caution is required.
Fuck rabies, man. Fortunately, a bat won't transmit via scratch. But even The smallest bite or transfer of saliva on an open wound can transmit it. If you encounter a bat and are 100% sure it didn't bite you, it's fine. But if you're only 99% sure, you're in for a world of hurt with the rabies series. That's why people who wake up with a bat in their room have to go through the series.
Bats can carry all sorts of diseases some of which can affect humans like rabies. However most of them don't, and they're protected species anyway so you're not allowed to touch them. If it does have a disease the best thing to do would be to stay as far away from it as possible and hope it goes away on its own. Either way the best advice is not to touch it.
I went spelunking with some friends once, and we were crawling through this section of the cave that was only about 4' tall. There were around 100 bats sleeping on the ceiling above us as we cautiously crawled past. Well, my crazy idiot friend thought it would be hilarious to wake them all up and started screeching like a banshee. All of the bats dropped down from the ceiling and started flying back and forth, inches from our faces. I was thinking that I'd kill my friend if any of us got bitten, but thankfully the bats completely ignored us and eventually flew off to who knows where. That same idiot went back to the cave a couple weeks later and caught one of the bats. We forced him to return it to the cave and release it. He was a fun guy, but prone to unpredictable, dangerous behavior.
