Bolingbrook police said officers responded to the home in the 100-block Enclave Circle at 2:48 a.m. on April 27. Police said an unknown person threw a brick through a bedroom window, and multiple derogatory, homophobic and racist slurs spray painted on the front of the home.
The graffiti also included a swastika and profanity.
Police said they believe the attack was targeted, not a random attack on the family.
An investigation is ongoing.
