My question involves criminal law for the state of: pa

On January 30th I bought an Xbox One S off of offer up app on a cell phone here is what the ad said

"Looking to sell my basically new Xbox one s. It comes with 2 games battlefield one (Digital) Minecraft also is included with bundle never used the code. I'm firm on my price due to I'm selling it to pay fines."

It look legit to me so I contacted the seller and we arrange the meeting through the app to the point where I gave him my cell phone number and he came to my home and I paid for it.

It is now February 11th and I got a text at 1 a.m. in the morning stating this

"Hi we have an issue, the Xbox one I sold you was given to me by someone and all of a sudden they want it back or they are reporting it stolen is there any way I can give you your money back for it or I'm gonna get in trouble.."

I am a 33 year old male with Asperger's Syndrome and I asked my support staff what to do they told me it's bestest to wait it out.

So my question is what is the best thing to do I'm kind of scared I don't want to be in prison for this as a side note I do have the guys information off the Xbox because he left me his account at least his address and stuff like that.

Should I go to the police with this or wait it out. Thank you for your replies and for reading my long message
