Deputies said Nicholas Clay Sereda took from his mother the quickest way she could have called for help.
As the drunk and disorderly 21-year-old rode in the passenger seat of his mother's Chevrolet Cruz, he ripped the rearview mirror off the windshield – which includes the vehicle's OnStar system – and threw it toward the backseat, according to the Hernando County Sheriff's Office.
"Call 911 now (expletive)!" he yelled at his mother, deputies said.
The two were riding north Tuesday along U.S. 19. Sereda's mother picked him up from a friend's house in Pasco County. By the time they crossed County Line Road into Hernando, a drunken Sereda turned violent, according to reports.
Deputies eventually arrested the 21-year-old Sereda on charges of aggravated assault, robbery by sudden snatching, domestic battery and criminal mischief.
Sereda, of 14495 Chicaric Road in Brooksville, pulled hard on his mother's seatbelt and pinned her to the seat, deputies said. He yelled profanities at her, kicked and broke the windshield and threatened her with a knife, according to an arrest report.
While holding the knife to her, he told his mother he would "kill her before the cops got there and that he would smash her face in and beat the (expletive) out of her," deputies said.
Sereda's mother made several stops "to seek shelter in stores," but the suspect would not let her enter any of the businesses alone and would follow her closely whenever she stepped out of her vehicle, according to an arrest report.
She eventually called a friend and asked to meet her at the Walgreen's at Spring Hill Drive and Barclay Avenue. She drove there, parked the car and went to her friend, but Sereda followed her, ripped the car keys from his mother's hand and told her she wasn't going anywhere, deputies said.
The sheriff's office was called and Sereda took off, but he was apprehended a short time later around 7:40 p.m., according to the report.
Sereda was transported to the Hernando County Jail and held without bond.
Court records show Sereda being convicted during the past couple years on charges such as violating a domestic violence injunction and obtaining property by means of a worthless check, but he also has had many other charges dropped, including battery and aggravated assault.
