Over 15 motorcycles were brought to a police station here on Wednesday and their owners questioned over the death of a 20-year-old woman, who was visiting home from the US, in a Bulandshahr road accident, police said.

Information has also been sought on all Bullet motorcycles registered in the district from the assistant regional transport officer (ARTO), they added.

The police said 15-20 bike owners were questioned.

The woman, Sudiksha Bhati, died on Monday morning near Aurangabad when she met with an accident while riding pillion on a motorcycle with her younger brother. She was pursuing a graduation course in entrepreneurship at the Babson College, Massachusetts (US), and was scheduled to go back on August 20.

Her family has alleged that the accident happened because two motorcycle-borne men were following her two-wheeler and harassing her.

Jitendra Bhati, the deceased's father, said on Tuesday: “Sudiksha had gone to see some relatives at her maternal uncle’s village in the Aurangabad area of Bulandshahar district (40km from Dadri) two days ago. She was returning with her brother on Monday morning when two youths on two Bullet motorbikes began chasing them.

“My son told me that they were not only passing lewd remarks but also making obscene gestures. They were also doing stunts on their motorcycles. This continued for about 3km. Then one of them overtook my son’s motorcycle and suddenly applied the brakes. My son’s bike hit the Bullet and Sudiksha fell on the road and suffered head injuries.”

Senior Superintendent of Police Santosh Kumar Singh said the road accident took place near the border of Charaura Mustafabad village in the morning of August 10.

According to eyewitness Hemant Sharma, a Bullet motorcycle in front of the two-wheeler in which Sudiksha and his brother were travelling hit the brakes due to a milk tanker coming from the opposite side, he said.

Because of this, the motorcycles collided, leading to injuries to Sudiksha, Singh said.

He added the woman's brother had not mentioned anything about harassment to the police at the time of the incident.

In a purported video that has surfaced on social media, Bhati's brother said, "We were on a motorcycle at a speed of 30 km per hour. The men on the Bullet were riding near us and applied brakes on their vehicle suddenly...The Bullet had 'Jat Boys' inscribed on its number plate and its number started with UP-13."

The Bulandshahr Senior Superintendent of Police has constituted a three-member SIT, led by Circle Officer (city) Diksha Singh, to probe the matter.

The district police has filed an FIR against two unidentified people on the basis of a complaint by Sudiksha's father.
