PLANT CITY, Fla. -

Deputies arrested a man who is accused of attacking his 75-year-old grandmother with a machete during a dispute at her home near Tampa.

The Hillsborough County Sheriff's Office says 34-year-old Anthony Griffith got into a physical dispute with Barbara Harvey on Saturday afternoon. He then grabbed a machete and slashed her face and upper body.

According to an arrest report, Griffith called 911 after the attack and explained what he had done. Deputies responded and arrested him without incident.

A sheriff's spokeswoman says Harvey was in intensive care on Sunday night at Florida Hospital. Her grandson faces charges of attempted first-degree murder and aggravated battery with a deadly weapon on a victim over 65.
