Bodycam video from a white US police officer who was suspended for wrestling a black woman and her daughter to the ground appears to show the officer using his foot to push the 15-year-old girl into a police car.

The footage was provided to The Associated Press today from attorneys representing Texas woman Jacqueline Craig, who had called police last month to report that a neighbour choked her seven-year-old son for allegedly littering in his yard.

The attorneys also provided internal affairs documents showing the officer had been disciplined for a previous use of force complaint when he allegedly used a Taser on a black teenager to end a foot chase.

Police spokeswoman Tamara Valle said the department could not authenticate the video or the disciplinary report.

Fort Worth police said they had dropped all charges against Ms Craig and her 19-year-old daughter, Brea Hymond, who had recorded the interactions between Ms Craig and Officer William Martin in a separate video they posted on Facebook in December.

Attorneys for Ms Craig said charges also had been dropped against Ms Craig's 15-year-old daughter, Jacques Craig.

The daughters were charged with resisting arrest and interfering with public duties. Ms Craig was charged with resisting arrest, failure to identify herself as a fugitive and three outstanding traffic warrants.

Police said that the neighbour, Itamar Vardi, has been issued a citation for misdemeanour assault by contact related to Ms Craig's son. Mr Vardi did not immediately return a call seeking comment.

Ms Craig's attorneys said they had hoped for more serious charges against the neighbour. They called the misdemeanour ticket "a slap in the face," noting the boy visited the emergency room and was given medication after the injury prevented him from sleeping.

The bodycam footage provided by Ms Craig's attorneys also depicts Mr Martin pushing Ms Hymond's arms, which were handcuffed, above her head from behind when she refuses to answer his question.

It also shows him pushing another young female who approaches the police car.

Those two incidents along with the use of his foot to push the 15-year-old into the police car were cited in a letter from Police Chief Joel Fitzgerald to the city's Civil Service Commission explaining the finding that Mr Martin had used excessive force in the situation and asking for his suspension.

The Fort Worth Police Department has denied media requests to release Mr Martin's bodycam footage.

Mr Martin has returned to work after serving a 10-day suspension that he's appealing with the city's Civil Service Commission.

Ms Craig's attorneys said the family would like to see the officer fired and criminally charged.

The internal affairs documents Ms Craig's attorneys provided to The Associated Press said Mr Martin was one of a handful of officers to respond to a trespassing complaint at a high school.

A foot chase ensued and Mr Martin fired his Taser twice, striking one of two black teenagers in the back as he fled.

The report said Mr Martin was ordered to undergo coaching with a supervisor for violating department policy that prohibits officers from deploying weapons to stop a foot chase, particularly if a suspect is not armed or posing a threat.

A phone message seeking comment from Mr Martin's attorney was not immediately returned today.

Ms Valle, the police spokeswoman, said the department does not release complaints against officers that do not result in a suspension or firing.

Mr Fitzgerald's report about the December incident said Mr Martin violated department policy by failing to thoroughly investigate, neglecting his duty, and being discourteous to the public and conduct prejudicial to good order.

The video also shows Mr Martin's conversation with Ms Craig and one of her daughters after he places them in the back of a patrol vehicle.

"Here's the deal. When somebody's under arrest, if anybody interferes, they go to jail too," Mr Martin told them.

"Well, I don't know this. I'm 15 years old," Ms Craig's daughter replied.

Ms Craig responds: "He got mad at me for saying what I said. That's why he did it. But it's all recorded, it's all recorded."

Police said that Mr Martin would not return to the same neighbourhood where the incident occurred.

That followed comments Mr Fitzgerald made earlier this month saying Mr Martin would return to the same community "to repair relationships."
