Winnipeg police released a short video of Thelma Krull walking the morning she disappeared, and said her glasses have been found.

She was last seen on Saturday morning in the Harbourview South area.

Several searches have been carried out to locate her, with police, family, friends and others helping.

Police released a short video showing Krull walking from her area of residence on the morning she disappeared. It can be seen here.

“New information has come to light to suggest that Thelma Krull may have been in the immediate area surrounding Valley Gardens Community Club between 7:00 a.m. and 10 a.m. the morning of Saturday, July 11, 2015,” said police. “As such, we are specifically requesting anyone who may have been in that area at the time, whether playing tennis, walking or going for a jog to contact police if they feel they may have observed Thelma or any suspicious activity.”

Police said her glasses were found around Valley Gardens. Officers found other items nearby but don't yet know if they belong to Krull.

Officers called for people with security cameras in the area to also review their footage of the hours between 7 a.m. and 10:30 a.m. on July 11.

"It is possible that morning she may have been walking within potential areas including the Valley Gardens area, the area of the 2000 block of Henderson Highway, the 1500 block of Regent Avenue West," said police.

"We are on day five and as each day goes by we get more and more concerned, for sure,” said Det. Sgt. Shaunna Neufeld.

Anyone with information is asked to contact the missing persons unit at 204-986-6250.

Krull's family thanked the public for its help in the search so far.

"This is Winnipeg. It's a great city and we need your help. So please, please if you have anything, call the police,” said Robert Krull, Thelma’s husband.
