My question involves criminal law for the state of: Michigan
when I walked out of the store i had taken a t shirt and i think it was an undercover shopper came out and said he knew i took the shirt and asked me to come over. so when he grabbed my arm i ran away. then the police showed up at my house about 3 hours later and arrested me for unarmed robbery. the shirt was less than 40 dollars. I did not push the guy is just pulled away and ran. will I get the felony charge of unarmed robbery? what should I do?
