Exeter City Council's rapid response cleansing team swung into action when a "considerable amount of excrement" was found on a pavement.
The team were alerted to the discovery next to the First and Last bus stop on Cowick Street last Friday by St Thomas councillor Rob Hannaford, after worried residents and businesses contacted him.
Cllr Hannaford said: "This was just horrendous; the mess was everywhere.
Because of the prodigious quantity we were unsure if it was animal or human waste.
As this is a such busy area I requested that a crew come out and action it as priority, which they did.
"It was all made much worse as the area has several well used hairdressing salons and it was very degrading for many local ladies who had come out for their regular appointments to then have to come into contact with the mess.
If anyone has any information about this incident please contact the police."
