The 23-year-old was arrested for allegedly filing a false police report a year ago, according to the family's attorney.
The attorney says police are making arrests for a case they're not prepared to bring to court.
On Friday, the man's mother, Charla Pendergrass, was arraigned on a charge in connection London's death. Charla was charged with lying to a peace officer during a violent crime investigation.
"If you go back to even yesterday, think about this: Your cameras here at Channel 7 were the only ones out front when Charla Pendergrass was arrested. And when have you ever seen, again, they did the perp walk. Normal protocol is, you know, you take somebody through the Sally Port. They want to do everything they can to destroy the reputation of my clients to make their case, a case which they do not have," said Defense attorney Terry L. Johnson.

During the arraignment, Wayne County Assistant Prosecutor Anna Merigian told the court that there is video evidence to show Pendergrass lied to police.
