A drama teacher who set up schools with a range of fake names has been jailed for nine years.
The 71-year-old was sentenced after pleading guilty to indecent assaults on boys aged under 13.
Detectives from the Met Police launched an investigation after two men reported being assaulted in the 1980s by a private drama teacher.
Glyn Davies was arrested on February 10 this year after detectives from the Met's Sexual Offences Exploitation and Child Abuse Command identified him as using a fake name, "Glen Knowles", which he used to run The Glen Knowles Drama Schools and Clubs in areas across Hampton Hill in Twickenham and Coulsdon in Croydon.
Davies, of Fir Tree Close in Bridgwater, Somerset was later charged on September 29 with two counts of indecent assault on two boys under the age of 13.
The 71-year-old was sentenced at Isleworth Crown Court to nine years in prison and he will remain on the sex offenders register for life.
Leader of the investigation at the Met Police, detective constable Helen Lawson, said: "Davies abused a position of trust and due to the large amount of children who attended his classes there are concerns that there may be other victims who are yet to come forward."
Davies was known to have run other drama schools in Kent and possibly in South London and also used other fake surnames, the Met said.
DC Lawson is urging potential victims to come forward.
She said "Davies also used the surnames Knowles, Krauss and Krauss-Davies during the 1980s.
"I would urge anyone who is yet to speak with police to contact us."
