(STMW) — Michael Giangrand wasn’t expecting to be attacked by a raccoon when he opened his rental unit at a Public Storage in west suburban Schiller Park on Sept. 11, 2013.

But he claims that’s exactly what happened.

Now, Giangrand is suing California-based Public Storage due to injuries he suffered by a surprise raccoon attack that happened after he opened the door to his storage locker, according to a lawsuit filed in the Circuit Court of Cook County Thursday.

Giangrand claims that Public Storage “failed to warn its customers that the storage units were not secure and that raccoons and other wildlife” had access to the units, according to the suit.

The lawsuit didn’t say what kind of injuries Giangrand suffered or if any of his belongings were damaged.

The suit claims negligence and is seeking at least $50,000 plus the cost of legal fees.

Calls made to his attorney and Public Storage were not immediately returned.
