(CBS News) LONDON — Detectives in London were to question two people arrested over the murder of British Army Drummer Lee Rigby, described Thursday by family and friends as a loving family man who always wanted to serve.

Both of the primary suspects were recovering from gunshot wounds received in a confrontation with police, and their conditions were not thought to be life threatening.

A man and a woman, both 29, were also arrested Thursday on suspicion of conspiracy to murder during the investigation into the slaying of 25-year-old Rigby, who was hacked to death in broad daylight in Woolwich, southeast London, on Wednesday afternoon.
