Shannon Peterson, who lives in Vancouver, visited her daughter, Akele Taylor, in September 2012,just weeks after Taylor had broken up with Carter.

Peterson testified Thursday afternoon, telling jurors thatduring her visit she was followed into a grocery store, at a restaurant and at the airport.

On one occasion, Peterson and Taylor were driving on Bow Trail when three people including Steve Walton, a woman who she believed to be Heather Walton and a third person, in a marked CPS vehicle boxed-in her daughter's car.

Peterson said her daughter was scared.

"See what's been going on there?It's non-stop," Taylor told her mother.

During the week she was staying with Taylor, Peterson said she noticed her daughter wasn't eating very much, was "very sad and stressed" during the visit and would often cry.

Adding to Taylor's stress was the fact that Steve Walton had somehow gained access to her apartment building, Peterson said. One time he banged on her unit door and then held it open when Taylor answered it.

"It was very intimidating," Petersontold jurors.

Carter who is said to be worth about $80 million allegedly directedthe Waltonsto participate in a"campaignto discredit and harass" Taylor, after their breakup in 2012, said prosecutor KatherineLove in her opening statement to the jury.

According to Love, Carter paid theWaltonsmore than $800,000 for their services in an effort to gain sole custody of the daughter he shared with Taylor.

Storage unit incident

Earlier on Thursday, Calgary police Const. Michael Phillips testified that on Sept. 12, 2012, he responded to a report of a break-in in progress at a self-storage unit.

When he arrived, he spoke withTaylor anddetermined it was her own storage locker.

Phillips then called the number which had phoned police to report the break-in andidentified the calleras Heather Walton.

The officer then noticed an SUV cruising the parking lot andran the plate, which came back as Carter, who he then confronted.

Carter told him Taylor had stolen hundreds of thousands of dollars worth of jewelry from him,was affiliated to a gang and was trying to have him killed.

Then Phillips received a phone call from Steve Walton, who told the officer he was a former CPS member. Walton asked the constable for information on the investigation he'd just conducted but Phillips refused.

McLachlanrefused to attempt drug deal

A former police detective who had left CPS in August 2012 testified thathe worked for the Waltonsthat same year, doing surveillance on Taylor and travelling to Saskatchewan and Vancouver in an effort to track down her relatives.

Shamus McLachlan saidafter those tripshe was asked by Steve Walton to attempt to buy drugs from Taylor. McLachlan said he refused because he didn't want to do anything illegal.

He was also asked to write a letter pretending to be one of Taylor's ex boyfriends in an effort to intimidate her. McLachlan said he decided not to send the letter before Steve Walton asked him to hold off.

Under cross-examination, McLachlan told Heather Walton's lawyer, Kelsey Sitar, that as aprivate investigatornothing about the surveillance assignments struck him as unusual.

None of the defence lawyers have had the chance to cross-examine Peterson. That will take place on Friday morning.

Alain Hepner represents Steve Walton while Gavin Wolchis Carter's defence counsel.

Aside from the harassment charge, the Waltons each face charges of bribing an officer, accused ofpaying police officers to access private information from CPS databases.
