A Fairfax County doctor convicted last month of statutory rape and of unlawfully prescribing drugs was sentenced to seven years in prison Friday.

According to testimony at his trial in February, Dr. Joseph S. Salama prescribed the tranquilizer Valium and the sedative methaqualone for a 14-year-old Alexandria girl in exchange for her sexual favors.

According to Assistant Commonwealth's Attorney Steven A. Merril Jr., Salama was taken to Fairfax County jail after Circuit Court Judge Richard J. Jamborsky revoked his bond. Jamborsky said Salama posed "a threat to the community," and that there was a likelihood that he would flee, according to Merril.

Salama could have received a maximum 10 years on the rape charge and one year and $1,000 fine or both on the charge of unlawfully writing a prescription.

According to Merril, Jamborsky said the only mitigating factors in Salama's case were his age, 58; lack of a prior record, and the fact that he has two children.

Salama maintained his innocence in an hour-long statement Merril said, just before Jamborsky delivered his sentence.

Salama was charged and convicted of one instance of statutory rape, which the prosecution said occurred Oct. 20, 1976.

A $1 million civil suit filed by the girl's mother against Salama is pending in Fairfax Circuit Cour.
