Last week, the 76-year-old fled to neighbouring India by helicopter last week as student-led protests flooded Dhaka’s streets in a dramatic end to her iron-fisted rule of 15 years, according to AFP.

The interim government led by Nobel laureate Muhammad Yunus has invited UN investigators to probe the violent "atrocities" that accompanied her ouster, which saw hundreds killed by security forces.

Yunus returned from Europe last Thursday to head the temporary administration that faces the monumental challenge of steering democratic reforms.

He took office as "chief adviser" to a caretaker administration -- all fellow civilians bar a retired brigadier general -- and has said he wants to hold elections "within a few months".

The interim cabinet said that UN investigators would arrive next week to probe "atrocities" committed during the protests that ousted her.

On the anniversary of the 1975 assassination during a military coup of Hasina’s father Sheikh Mujibur Rahman last year, huge rallies around Bangladesh marked the occasion.

"Fugitive and dictator Sheikh Hasina has ordered her goons and militia forces to come to the site so they can produce a counter-revolution," Imraul Hasan Kayes, 26, told AFP.

"We are here to guard our revolution so that it doesn’t slip out of our hands."

With no police in sight, hundreds of men -- most of them not students -- formed a human barricade across the street leading to Hasina’s old family home, where her father and many of her relatives were gunned down 49 years ago.

The landmark was a museum to her father until it was torched and vandalised by a mob hours after Hasina s fall.

Several people that the crowd suspected of being Awami League supporters were thrashed with sticks, while others were forcibly escorted away.

Hasina, in her first public statement since her abrupt departure, asked supporters this week to "pray for the salvation of all souls by offering floral garlands and praying" outside the landmark.

She was accused while in office of establishing a cult of personality around her father, who appears on every banknote.

Hasina changed the constitution to require a portrait of him appeared in every school, government office and diplomatic mission.

"Her government even made it an offence to criticise him online, punishable with up to 10 years in prison," Tom Kean of the International Crisis Group told AFP.

"While many people still have great respect for Sheikh Mujibur Rahman and his achievements... this had curtailed any real debate over his legacy."

Thousands of civil servants were required during her tenure to join public demonstrations on the anniversary of her father’s death.

Awami League organisers would also set up temporary public address systems around Dhaka to blare out Mujib s old speeches as well as devotional songs praising his leadership.

The interim government cancelled observance of the politically charged holiday on Tuesday, requiring bureaucrats to remain in their offices.

And the prevailing sounds in the city of 20 million people on Thursday were the horns and engine hums of its perennially gridlocked traffic.
