MIAMI -

The Miami-Dade State Attorney's Office on Thursday dropped charges against two brothers, including one who was seen on video being punched by a Miami police detective after he crossed crime scene tape surrounding his brother's body.

Police arrested 28-year-old Anthony Walker (pictured left) and his 27-year-old brother Antwan (pictured right) after the two scuffled with officers and tried approaching the body of their brother Brandon Walker on April 9.

"Very shocking to see someone whom I love so much in that position. Never in my life did I think I would see that. Words still fail me with what happened that day," said Anthony Walker. "What my intentions were was to grab my brother (Antwan) and that was secondly on my mind -- rather than seeing my little brother (Brandon Walker) there -- was grabbing my brother who was also overcome with grief, as we all were."

Video showed Miami Police Detective Fernando Bosch grapple with Anthony Walker and punch him several times. After they separated, Bosch punched Anthony Walker again, knocking him down.

Miami-Dade State Attorney Katherine Fernandez Rundle agreed to drop their charges. Anthony Walker had been charged with battery on a law enforcement officer and resisting an officer with violence. Antwan Walker had been charged with resisting an officer without violence.

"This is another chapter in which God has again proven himself to me. I trusted in him the whole time and he's again prevailed on my behalf," said Anthony Walker. "I'm a very humble young man and things did take place, but right now, I'm just grateful that this hurdle has been jumped."

Walker said he still struggles with what happened that day.

"My little brother was the life and laughter of my family. I still get teary eyed when we speak about him. It's very, very difficult. But as my attorney has stated, if anybody knows anything about that, please help," he said.

Fernandez Rundle also declined to file charges against Bosch.

"Any potential criminal investigation into police action at the scene will be declined and the matter handled administratively by the City of Miami Police Department," Fernandez Rundle wrote in a letter. "Though your client and his brother have not made a formal complaint to the City of Miami Police Department Internal Affairs Unit, they are aware that the actions of Det. Bosch are being examined and they will cooperate with Internal Affairs personnel."

Anyone with information in Brandon Walker's fatal shooting is asked to call Miami-Dade Crimestoppers at 305-471-TIPS.
