Baker, who plays for the New York Giants, went to the main jail at the Broward Sheriff Office (BSO) in Florida on Saturday morning, according to the BSO website.
Baker and Dunbar were at a house party on Wednesday where several participants allege that the two soccer players stole thousands of dollars in cash and precious watches while they were armed, according to an arrest warrant.
Baker is charged with four counts each of aggravated assault with a firearm and armed robbery, the BSO prison website said. No court appearance is scheduled for him.
Dunbar faces four counts of armed robbery with a gun, police in Miramar said.
CNN contacted a lawyer for Baker. Dunbar’s lawyer Grieco said in an Instagram post that the charges against his client “do not hold water”.
“His career and reputation were put at risk following an overzealous @miramarpd who was so excited to arrest a professional football player that they tweeted their celebration and even labeled his employer in their “unprofessional” virtual touch dance, Grieco read on.
