A council has apologised for issuing an advert for a "female, white and non-Muslim" taxi driver to take a disabled child to school.
Northamptonshire County Council has begun an investigation after it issued the advert to private taxi companies.
It is believed the conditions were made by the child's parents.
The council said: "We apologise for this error of judgment which resulted from trying to address the specific needs of an individual child."
'No malicious intent'
The advert stated: "The contractor must provide the escort. Please note that the escort must be female, white and non-Muslim."
A council spokesman said: "We're confident on the basis of our initial investigations that there was no malicious or discriminatory intent.
"The council takes equalities very seriously and we will not tolerate any practices in this organisation which discriminate against any group or community."
