Cambridge University students have rallied behind an academic who said racism at one college is "widespread".
Priyamvada Gopal, pictured, claimed porters at King's College frequently "hassled" non-white staff and students at the gates, amounting to "racial profiling".
Since posting about the issue, current and former students have said they had similar experiences.
A university spokeswoman said it "abhors racism" but its investigation found no wrongdoing by staff.
The lecturer hit the headlines earlier this week when she said porters at King's had repeatedly refused to use her academic title of "Dr" and had spoken to her in a harsh and sarcastic tone.
She described the incident as a "small issue" but said it was "symptomatic of a wider problem" at the university.
The academic, who specialises in post-colonial literature, announced in a Twitter post that she would be be refusing to supervise any students at the college in protest.
