Amongst them were PKR deputy president Azmin Ali, PAS vice president Mahfuz Omar, Hulu Kelang rep Shaari Sungib and Solidariti Anak Muda Malaysia (SAMM) chairperson Badrul Hisham Shahrin.
Prayers and chants of “Allahu akbar” punctuated the duration of the procession.
Along the way three police cars on separate occasions interrupted, and the mourners responded chanting “Allahu akbar” to the cops.
Earlier, many Pakatan and Bersih leaders paid their respects at Surau Al-Muqarrabin close to the deceased's home in Keramat, Kuala Lumpur as early as 9am.
PKR de facto leader Anwar Ibrahim and daughter and PKR veep Nurul Izzah Anwar, PAS deputy Mohamad Sabu and VPs Husam Musa, Mahfuz Omar and Bersih 2.0 chair S Ambiga were amongst those present.
The surau was packed when the body was being bathed and prepared for burial, with PKR exco member Badrol Amin Baharon leading the prayers.
The many leaders present were visibly saddened and some were visibly emotional.
In particular Ambiga and Nurul Izzah (below, left and right with Rusni, centre) with wept as they consoled the widow Rusni.
“This should not have happened. He (Baharudin) is a hero,” said Ambiga briefly before tears overwhelmed her.
Meanwhile fellow Bersih leader Maria Chin Abdullah added, “Bersih regrets that this has happened. It shows that the police do not respect the rakyat.”
“The rakyat had the right to be there (at the rally),” she said, choked with tears and unable to continue.
The heavy-handed police action to stop the protestors yesterday were also a talking point during the funeral.
Speaking to reporters after the burial, PKR Wanita VP Gan Pei Nei condemned the police action in particular firing tear gas into Tung Shin hospital at Jln Pudu.
Gan, who is also Rawang assemblyperson, claimed that she was in the hospital compound when the incident took place and witnessed it.
She called on members of the public who had photos of the incident to contact Bersih 2.0 or Pakatan personnel.
Meanwhile Mahfuz and Salahudin Ayub said they were lodging a police report on their detention.
Their lawyers, they said, will attempt to seek redress.
