Police are hunting this woman after a small box of human faeces was left outside an MP's office.
The "offensive item" was found outside Siobhan Baillie's constituency office in Stroud, Gloucestershire Constabulary said.
Officers would now like to speak to the woman shown - dressed in pink trousers - in connection with alleged harassment of the Tory MP.
CCTV footage showed the woman walking toward Mrs Baillie's office, police said.
The incident was reported shortly after 1.30pm on Wednesday, November 2.
Gloucestershire Constabulary said: "Police have released CCTV footage of a woman they would like to speak to in connection with the harassment of an MP.
"An offensive item was left outside of the constituency office of Stroud MP Siobhan Baillie.
"The incident involving a small box containing human excrement was reported shortly after 1.30pm on Wednesday 2 November.
"Investigating officers have now identified a woman on CCTV who they would like to talk to further in relation to the incident.
"In the footage, the woman is seen wearing pink trousers and walking towards the MP's office.
"Anyone who can identify the woman or who has information which could help the investigation is asked to contact Gloucestershire Constabulary through the website, quoting incident 212 of 2 November."
Mrs Baillie became the Conservative MP for Stroud in 2019.
Speaking to the BBC about the incident earlier this week, she said she found it "difficult to understand" the perpetrator's motivation.
She said: "There are plenty of ways to make a point about politics or governments without resorting to putting excrement in a box."
