(Cover) - EN Showbiz - Kris Jenner believes a prank caller was responsible for sparking a child services investigation at her home on Friday, according to reports.

Child Protection Services officers visited the Los Angeles home of Kris and Bruce Jenner on October 26.

The visit followed allegations the couple's youngest daughters, 16-year-old Kendall and 15-year-old Kylie, were being abused.

A follow-up visit was reportedly scheduled for Monday afternoon before the case could be closed.

No evidence of abuse was found by the Los Angeles County Department of Children and Family Services, TMZ reports.

According to the website, Kris thinks a prank caller is responsible for the ordeal.

"[The complaint was] ridiculous because Kylie wasn't even in the country the day the caller claimed she was in danger. She was in the Philippines," a source told TMZ.

The matriarch has reportedly hired a private investigator to look into the matter.

A source said Kris believes a tabloid reporter may be responsible for making the allegations. (C) Cover Media
