An attorney representing former Texas Police Officer David Eric Casebolt says that he is sorry for pulling his gun out on unarmed teenagers at a pool party and manhandling a 15-year-old girl in a bikini.

Video of former McKinney, Texas Police Cpl. David Eric Casebolt's actions at the teenage pool party has since gone viral. In the video, Casebolt is seen yelling, cursing and detaining black teenagers who were attending a party at the Craig Ranch North community pool last Friday. At one point, the ex-cop is seen aggressively throwing a 15-year-old girl to the ground, before shoving her face into the grass. She then began calling out for her mother. However, when two teen boys tried to come to her aid, Casebolt pulled out his firearm. He then placed both of his knees on her back.

On Tuesday, the veteran officer resigned from the police force amid an outcry of public outrage across the country.

During a press conference in Dallas on Wednesday, Casebolt offered an apology through his lawyer, who said that the officer had been under stress earlier in the day before he got to the pool party, reports The New York Times.

His lawyer also told reporters that the 7-minute "video that everyone has seen only depicts a small part of Eric's actions that day," said attorney Jane Bishkin.

According to her, the 10-year veteran had responded to two suicide calls earlier Friday. As a result, he was "reluctant to respond" to the call about a fight at the pool party, his attorney said. However, he felt it was his duty to go to the scene.

"With all that happened that day, he allowed his emotions to get the better of him," Bishkin said, reports CNN. "Eric regrets that his conduct portrayed him and his department in a negative light. He never intended to mistreat anyone, but was only reacting to a situation and the challenges it presented. He apologizes to all who are offended. That day was not representative of the 10-year service to the community of McKinney, and it is his hope that by his resignation the community may start to heal."

She also said that race was not a factor in how the officer responded.

"He believed that those who fled were possible suspects," Bishkin said. "He was not targeting minorities. In fact, he also detained a white female who you do not see on the video. His effort to gather information was hampered by some teenagers who were instructing others to defy police instructions."

Back in 2008, Casebolt was sued by a black man who accused him of racially profiled him and using excessive force during his arrest, the International Business Times reports. The civil suit was later dismissed.
