A former police spy who is now a lecturer at St Andrews University is facing fresh demands for him to be sacked.
Dr Bob Lambert was exposed in 2011 as a former undercover police officer.
He has been accused of involvement in undercover incidents while infiltrating the Animal Liberation Front, including setting fire to a Debenhams shop.
Campaigners have now urged university principal Professor Louise Richardson to terminate the contract of the terrorism expert, who denies the allegations.
Signatories to a letter, including campaigning journalist George Monbiot, claimed Mr Lambert was no role model and his conduct meant he was “supremely unsuitable for teaching and shaping the thoughts of others”.
They accuse him of “years of deliberate, strategic abuse of citizens and undermining of legitimate campaigns”.
Their demand comes as a judge-led inquiry into undercover policing is about to begin.
During the 1980s Mr Lambert, who was awarded an MBE for his police service, infiltrated animal rights and environmental groups for the Metropolitan Police Special Demonstration Squad.
He has previously admitted having sex with women linked with his targets, even fathering a child with one activist who later received compensation for trauma.
Intelligence gathered by Mr Lambert helped to jail two men behind coordinated attacks on two branches of Debenhams.
Mr Lambert’s first public engagement at a talk in St Andrews after his past was revealed was disrupted by activists.
A university spokesman said: “Bob Lambert is employed by us as a part-time lecturer in the School of Inter-national Relations and the Centre for the Study of Terrorism and Political Violence.
“He has been entirely open with the university and his students about his past.
“His teaching is highly valued by students.”
Dr Lambert, who has received awards for his support of Muslim community groups and work in counter-terrorism, was unavailable for comment.
