PARENTS and residents of Bundaberg North have been advised to be vigilant after a man exposed himself to an elderly woman at the weekend.

Bundaberg North State School sent a letter home to students to warn families of the incident which occurred outside the school about 9am on Sunday.

The letter said a school staff member was flagged down by a distressed elderly lady who said she had been walking to the IGA when a man came out of the drain that goes beneath the road and exposed himself to her and he was also performing other "lewd behaviours".

"Given the number of children who frequent this area both before and after school and on weekends, I thought it was very important that you have this information," school principal Veronica Geiger said in the letter.

The NewsMail contacted the school and was advised they were not able to comment and was referred to the Queensland Education media department.

A spokesman for the department said schools deal with issues such as stranger danger on a regular basis and are always looking out for the welfare and safety of students.

Bundaberg police confirmed a call was reported about 9.40am and a patrol car was sent to the area but was not able to locate anyone.

Bundaberg residents took to social media saying a lady had also been flashed on Hurst St and another said they had heard reports of a person performing the same acts in the Botanic Gardens.

Detective Sergeant Cameron Schneider said this was the first case the police had been made aware of in some time.

"We don't normally see this type of behaviour," Det Sgt Schneider said.

"This incident had nothing to do directly with the school.

"We urge people if they see this type of behaviour to report it to the police."

He said if a person was found to be behaving in such a manner they could be arrested for wilful exposure.
