Updated at 3:25 p.m.: Revised to include Craig family's news conference.

The Fort Worth police officer who was seen in a viral video forcing a mother to the ground and detaining her daughters has been suspended for 10 days without pay.

The officer was notified of the punishment Monday morning, Fort Worth Chief Joel Fitzgerald said. KXAS-TV (NBC5) has identified the officer as William A. Martin, a 10-year veteran of the force.

The case has been sent to a Tarrant County grand jury to determine whether criminal charges should be filed against anyone.

Critics have accused the officer, who is white, of racism against the black family. Fitzgerald, Fort Worth's first black police chief, said the punishment was ultimately his decision, even though not everyone in the chain of command agreed.

"Officer Martin is contrite," the chief said at a news conference Monday. "He's ready to get back to work. He's very sorry for what has transpired."

But Jacqueline Craig was in disbelief over the decision, her attorney Jasmine Crockett said.

" 'You you would get more justice if someone kicked a dog,' " Crockett said Craig told her. She added that Craig had been crying since learning of Martin's punishment.

Craig's 19-year-old daughter recorded the encounter with Martin on Dec. 21, when Craig called police to complain that a neighbor had choked her 7-year-old son. Craig was taken aback by the officer's response.

"Why don't you teach your son not to litter?" he asked her.

Craig yelled at Martin, and he wrestled her to the ground by pressing a stun gun into her back after the woman's 15-year-old daughter tried to get between them. Then he handcuffed the teen and her older sister, who cursed at the officer as she filmed.

Craig and her two daughters face charges of interference with public duty, resisting arrest, disorderly conduct and failing to provide identification, according to Lee Merritt, another family attorney, who has accused the officer of racism.

Merritt said at the news conference that the Fort Worth Police Department sent a clear message by giving Martin a "10-day vacation."

He said the decision means the African-American community cannot trust Fort Worth police, that it is OK for members of the community to assault black children, and that police are using an "us vs. them" mentality — that officers will choose to protect themselves over residents.

Merritt said the family "will continue to pursue justice" by asking Tarrant County District Attorney to charge Martin and the neighbor, and to drop the charges against Craig and her daughters. He also said the family was prepared to pursue action in civil court.

The department found that Martin had violated some of its rules. Fitzgerald cited neglect of duty and discourtesy, noting also that there was "some inappropriate contact with two of the females." Other findings included excessive force, failing to thoroughly investigate and conduct prejudicial to good order.

But there were actions Martin took that were legal and will be assessed by the grand jury, Fitzgerald said, noting that the department's decision to keep him employed was not an endorsement of what he did.

"The department keeping him is not sanctioning bad behavior," he said. "People make mistakes."

The chief said Martin is eager to go back into the neighborhood where the incident occurred and repair relationships. He said the officer also will undergo training.

"Sometimes people are going to be displeased with us, but more than likely, they'll be willing to work with us," Fitzgerald said.

In a letter to the city's Civil Service Commission explaining the suspension, Fitzgerald wrote: "Pursuant to the incident, and his actions, media coverage portrayed Officer Martin and the Fort Worth Police Department in a negative light that generated justified unfavorable criticism towards both."

But Fitzgerald continued, saying that despite Martin's errors in judgment, "It is my belief that he has a future as a Fort Worth Police Officer and that his actions do not warrant an indefinite suspension."

Mayor Betsy Price called the encounter in the viral video an isolated incident.

"It is not indicative of the way Fort Worth police officers do business," she said Monday.

Officials said the internal investigation took into account the Facebook video plus footage from Martin's body camera and car camera, as well as video from other responding officers.

It's unclear when the grand jury will review the case. A spokeswoman for the Tarrant County district attorney's office said it's still working out the panel's calendar.

Community activists planned a rally for 6 p.m. Monday at Fort Worth City Hall to protest to police department's decision.
