A MARRIED man who had sex more than a dozen times with his teenage sister-in-law who became pregnant as a result was jailed for 18 months yesterday.

The security supervisor pleaded guilty to two of 15 charges of having sex with a girl under 16 between November and December 2007.

District Judge Jill Tan, who took 13 other charges into consideration, told the accused he was not only twice the girl's age, but also her brother-in-law.
