Detectives detained former MP Sultan Mohammad Mansur Ahmed from the immigration section of Hazrat Shahjalal International Airport in Dhaka early Monday morning.

Mansur, also ex-vice-president of Dhaka University Central Students' Union (DUCSU), has been detained for quizzing due to some allegations, said DMP Additional Commissioner and Detective Branch chief Rezaul Karim Mallik.

Necessary actions will be taken after the interrogation, he added.
