KISSING the back of a woman's hand may be an age-old gentlemanly form of greeting - when permission is granted.

But when a teenage girl was suddenly approached by a stranger who planted an uninvited kiss on her hand on Sept 7, she complained to her father, who then called the police.

On Tuesday, Seah Boon Teong, 36, who works as a security officer, was sentenced to six months jail in a district court for outraging the modesty of the 19-year-old girl.

The dishevelled man who has been remanded since Sept 9 stole a quick glance around the courtroom as he was led away by police officers.

The girl was walking her dog in front of the Buona Vista Swimming Complex that morning, according to court documents.

Seah, who was also walking his dog, suddenly approached the girl and held on to her left shoulder to get her attention.

He then held her left hand and kissed the back of it. Outraged, the girl pulled her hand away and went home.

She told her father about what had happened and both of them went to look for Seah.They found him still lurking in the vicinity of the swimming complex.

While they trailed him, the girl's father called the police who later arrested Seah.
