Officers arrested a 44-year-old man from Ipswich on suspicion of supplying a controlled drug, and have released him after questioning.
A 17-year-old has been charged with murder and will next appear in court on 12 April. Five other people have been arrested.
Mr Saunders, who was originally from Surrey, died from a single stab wound to the abdomen.
Three males - two from the Colchester area, aged 17 and 18, and a 15-year-old from Bury St Edmunds - were arrested on suspicion of assisting an offender on 20 December.
A man, 20, from Colchester, was also arrested on suspicion of assisting an offender on 25 January.
