A 21-year-old man pleaded not guilty Monday to charges that he assaulted his wife and a child at their Whidbey home.

Prosecutors charged Francisco J. Robles in Island County Superior Court Sept. 9 with assault of a child in the third degree and fourth-degree assault. Both counts were charged as domestic-violence-related crimes.

Earlier this month, the woman reported to the sheriff’s office that Robles hit her after accusing her of cheating on him based on a spam Viagra email she received, according to the deputy’s report.

The woman told the deputy that Robles assaulted her and her two children numerous times before, but she was afraid of him and waited until she got away from the residence to call the police; she said he hit both the 3-year-old and 6-year-old hard enough to bruise them.

The woman said she noticed a large bruise on the 3-year-old child’s inner thigh. The girl told her that Robles hit her with a belt, according to the report.
