Trap it and get rid of it.
Raccoons will breed and start digging up any gardens you have. Not to mention that they can find their way into just about anything. Don't be surprised if your city-issued trash can is infiltrated and trash is strewn about soon.
Also be careful that they don't get into your house, they'll use a dog door, or your chimney (if it's not capped). They got into the attic of my mom's house and had babies, she had to wait for the momma raccoon to move the babies out of the attic naturally before she could get the trapper to come and get the momma.
Raccoons are like little kids, they'll get into all your shit if you don't keep an eye on them. Luckily it's easier to get rid of a raccoon then it is a kid
