A Toronto mother has been ordered not to have any contact with her son after police accused her of helping him conceal evidence linked to a homicide investigation that led to his arrest.

Hyacinth Moore received the order in a courtroom on Thursday, one week after her son was charged in a series of shootings and robberies which date back to 2010.

It is alleged she helped her son, Mark Garfield Moore, destroy evidence connected to the sweeping homicide and robbery investigation in which he's been charged.

Mark faces more than 50 charges including four counts of first-degree murder in "Project Summit," an investigation that explored the possible link between almost a dozen unsolved cases from last year.

Toronto police have linked the deaths of four Toronto men – Jahmeel Spence, Courtney Facey, Mike James and Carl Cole – to a series of robberies and shootings.

Moore has publicly defended her son's record, telling CTV Toronto's Tamara Cherry last week that she believes her son is innocent.

"I'm not saying that Mark is perfect," she told CTV Toronto. "But at the same time there still is a vendetta going on."

The 49-year-old Toronto woman was arrested Wednesday and charged with accessory after the fact, obstruction of a peace officer, conspiracy to commit an indictable offence and accessory after the fact to murder.

Three other men were also arrested as part of "Project Summit" and have been charged in connection to an alleged firearms and ammunition trafficking ring.
