"Female supporters have also since contacted us to state they were asked by female stewards if they could feel their bras if they confirmed that they were underwired. The supporters were made to feel uncomfortable and when they replied they would 'rather not' they were 'reluctantly' let into the ground.
"This act would effectively constitute a sexual assault and these types of searches are unlawful. If deemed necessary, although we cannot see how feeling an underwire in a bra could be deemed so unless acting on previous intelligence, then any fans in question should have been taken to a private area of the ground to be searched by a female steward rather than being searched in full view of male stewards, fans and police.
"We are not aware at this stage that any previous intelligence contributed to these types of searches being implemented against female supporters."
The letter also claimed full body searches were carried out on children as young as five, with stewards branded "antagonistic".
Stevenage responded by announcing they had launched an internal investigation, while the EFL said it was looking into the matter as well.
