He will be eligible for parole after serving four years and one month of his sentence, backdated to July 25 last year when he was taken into custody.
Neil Sachman sexually assaulted a 14-year-old girl, after pulling her into bushes near a railway station in Greenwood, in the city's north on 25-7-2010.
Pleaded guilty to 1 count of deprivation of liberty- 3 counts of aggravated indecent assault-1 count of aggravated sexual penetration without consent.
The court heard Samit followed the woman as she walked home in January 2011.
He pulled her into bush in Old Broome and assaulted her, leaving the 28 year old with extensive cuts and bruises.
"Your conduct caused considerable distress and anxiety to the victim, and has also had a long-standing impact upon her, causing anxiety and loss of confidence and restriction in her social and work activities," Chief Judge Martino said of the stalking matter.
Sachman was also sentenced over a crash on South Street, Kardinya, when he was driving without a valid licence.
Samit was yesterday sentenced to six years and eight months in jail.
Police have applied for him to be registered as a dangerous sex offender, in light of his prior convictions for similar sex assaults.
The District Court was told he asked the girl for the time before putting his hand over her mouth and dragging her into secluded bushes south of the train station.
He forced the girl to kiss him, fondled her breasts and sexually penetrated her before masturbating over her legs.
Chief Judge Martino accepted that Sachman's guilty pleas showed a willingness to facilitate the course of justice.
