Midland students are being recruited by Islamic fundamentalists who are grooming them to become extremists, a Birmingham MP claimed.
Groups such as Hizb ut-Tahrir and Al-Muhajiroun are targeting students at university and college campuses in the region, said Khalid Mahmood.
Aston University said it shared the MP's concerns and admitted it had contacted security forces in the last month about the recruiting activities of extremists.
But Hizb ut-Tahrir rejected the claims against it, saying it was willing to address any "legitimate concerns" about its activities.
Mr Mahmood, Labour MP for Perry Barr, said the universities of Birmingham, Aston and Wolverhampton were being targeted along with regional colleges.
"What they do is try and get the young people who are in further or higher education who have an issue and want to learn about their religion," he said.
"They start off with positive points but slowly scoop them away and bring in fundamentalist and extreme views.
"Most of the parents who have lost kids through this say they became alienated because they are told their parents aren't practising the religion properly."
Mr Mahmood claimed once youngsters were hooked, other people then got involved in "steering them away from the mainstream into a very isolated sector".
"Fortunately a lot of young people, while they do go to the seminars, don't go for the whole remit.
"You only get a few that go all the way but as far as I am concerned it is enough given the effects it is having as we saw last month."
Professor Mike Wright, vice-chancellor of Aston University, said his institution was aware of the activities of various groups. "I share Khalid's concerns," he said.
"There is a list of extremist groups which we won't allow access to university facilities. It's not just Muslim groups, there are all sorts of groups.
"Where it becomes difficult is when they don't approach us and ask if they can come on campus."
Prof Wright said there had recently been an occasion when the university felt concerned enough to contact security forces. "We have had to do that recently about a month ago. All of the universities have threat contact points. We get a very swift response.
"If we find out something like this is going on we take action to stop it."
A spokeswoman for the University of Birmingham said it was not aware of any specific targeting taking place. "We take an assertive stance with regard to tolerance which we actively monitor," she said.
Al-Muhajiroun has in the past called for the overthrow of the British Government and wants to wants to establish a Muslim state in the UK.
Hizb ut-Tahrir is banned in Germany, Holland and Russia, and the Government has been under pressure to institute a similar ban.
Dr Imran Waheed, a Birmingham doctor and British media representative for Hizb ut-Tahrir, rejected Mr Mahmood's criticisms.
"Khalid often confuses us with other organisations and attributes quotes to us that were not said by us," he said.
"I have told him that we are civilised people and if there are things that people do not agree with in our dealings with youth, we are willing to look at any legitimate concerns.
"Hizb ut-Tahrir connects very well with youth but we seek to channel their concerns into seeking political solutions rather than taking up arms or making emotional outbursts."
Dr Waheed said the group's recent conference, at Aston University, promoted a "very responsible view on the role of Muslim women in 21st Century Britain".
