Farhan Moon, 19, a student of Tejgaon College, got on a rickshaw by which the 19-year-old was going towards Asadgate from Farmgate, she told that.
When she was on the rickshaw Farhan teased her standing behind the rickshaw, she alleged.
But the boy refused the allegation of teasing the girl.
Later, the teenager informed police patrolling the area and the law enforcers arrested Farhan after a chase.
Sher-e-Bangla Nagar police Sub-inspector Saiful Islam said the woman filed a complaint against the man who denied the allegation.
Farhan was not her acquaintance and she had no enmity with him, police quoted the female student as saying.
