Richards' addiction to heroin delayed his arrival in Toronto; the other members had already arrived. On 24 February 1977, when Richards and his family flew in from London, they were temporarily detained by Canada Customs after Richards was found in possession of a burnt spoon and hash residue. Three days later, the Royal Canadian Mounted Police, armed with an arrest warrant for Anita Pallenberg, discovered of heroin in Richards' room. He was charged with importing narcotics into Canada, an offence that carried a minimum seven-year sentence.
