"It is evident that a violent crime was committed," Scott Gleason told CBC News. "It should be investigated."
Gleason is representing Scott MacIntyre, a former relative of the Ford family, who filed a lawsuit against the mayor on Wednesday.
MacIntyre, the former common-law spouse of Rob Ford's sister, Kathy, claims he was beaten in the spring of 2012 while he was in jail on charges of threatening the mayor.
MacIntyre's lawsuit alleges Ford conspired with some of his former high school football team colleagues to try to silence him over what he knew about the mayor's private activities.
"I'm pleased to hear that the police and ministry officials are prepared to investigate the brutal treatment of our client. I don't know why it took almost two years for them to become interested," Gleason told CBC News in an emailed statement.
But Toronto police spokesman Mark Pugash said Friday that the TPS is not investigating because MacIntyre has not filed an official complaint.
"If he files a complaint, or reports a crime, we'll investigate," Pugash said.
Police will not commence a criminal probe simply because MacIntyre has filed a civil lawsuit, he added.
The allegations against Ford have not been tested in court. The mayor's criminal lawyer, Dennis Morris, said Wednesday the allegations are "without factual foundation."
Ford has 30 days to file a statement of defence.
