Ferdinand, 32, was watching television pictures of the violent scenes on Monday night which saw vehicles and property go up in flames and shops looted, and suggested the Army should be brought in to quell the disorder.
He wrote in three consecutive messages on Twitter: "The scenes on Sky news right now are shocking..what is this all in aid of?? Innocent peoples [sic] homes + livelihoods have gone up in smoke-why?
"It seems these kids/people have no fear or respect for the police....maybe the army will get that respect??
"And I am not saying bring violence, I am saying the presence of the army may make these kids/people think twice about continuing this??"
Rooney wrote on Twitter: "These riots are nuts why would people do this to there [sic] own country. Own city. This is embarrassing for our country. Stop please."
