The warning was given by the Municipal Information Officer, Ms Elizabeth Afia Ansaah at a meeting with the Information Centre operators in the Municipality.
The meeting was organised by the Municipal Assembly following public complaints about the excessive noise they made in the Municipality.
Ms Ansaah urged the Operators to use their channels to educate the public rather than always advertising herbal preparations.
She said all the Information Centres needed permit before they could operate in the hours of 0500 hours to 0700 and 1500 hours to 1900 hours daily and only one Information Centre could be in a particular area or community .
Ms Ansaah explained that the Information Centres had a responsibility to educate the people in their communities about policies of government, child labour, drug abuse and other social vices.
She said staff of the Assembly and the Environmental Health Department would be going round regularly to check the activities of the Centres.
