The assault happened between 2 a.m. and 3 a.m. on Feb. 18. Police say a man hit another man repeatedly with a shovel near the entrance of the store.
The victim survived and has since been released from the hospital, and police believe the suspect and victim may have known each other.
The victim has not cooperated with police as far as naming the suspects, so police are looking for witnesses who may have seen the assault.
Anyone with information should call the Fruitport Township Police Department at (231)-865-8477 or Silent Observer at (231)-72-CRIME.
