Police charged two of activist Winnie Mandela's bodyguards with murder, kidnapping and assault Tuesday in the abductions of four youths, including a 14-year-old black boy who was later found stabbed to death.

Police spokesman Lt. Col. Lourens Haasbroek identified the two men as Jerry Richardson, 41, the coach of Mrs. Mandela's controversial Mandela United soccer team, and Jabu Sithole. They appeared in court Tuesday but the case was postponed until next week and they entered no plea.Richardson and Sithole were two of the four blacks apprehended before dawn Sunday during an exhaustive police search of the residential compound of Mrs. Mandela - wife of jailed African National Congress leader Nelson Mandela - in the sprawling black township of Soweto on the outskirts of Johannesburg.

The other two, described as youths, were not charged and are expected to be released into the custody of their parents, the police spokesman said.

Richardson and Sithole were charged with the murder of Stompie Moeketsi Seipie, 14, who was one of four youths taken by the soccer team from the Methodist Church of white Rev. Paul Verryn on Dec. 29.

According to the Methodist Church, all four youths were "severely assaulted and held against their will" in defiance of community appeals to Mrs. Mandela to release them. Seipei was separated from the group on Jan. 1 and his decomposed body was found five days later. His body was identified only last week and and authorities said his jugular veins were slashed.

The three other youths were released on Jan. 16.

Mrs. Mandela has denied allegations of personal involvement in the beatings and has insisted the boys were taken from the church for their own protection because they had been sexually abused by Verryn.
