I feel the wheels locked due to a handbrake turn gone wrong.
Experienced truck and bus drivers often pull and immediately release the handbrake to induce a over steer when just steering and brake alone cannot avoid some infringement in their path. This is called handbrake turn in driver language.
The speed at what the driver moves the wheels to full LH and back in RH direction is impossible without a power steering vehicle.
That is called steering in the direction of the skid, and only some one who has retained his presence of mind throughout the incident would do it.
Without the steering in the direction of the skid the bus would have toppled over on its RHS side.
As Miyer writes in #28917 the tie rod gives away due to the stress at 11 seconds.
I guess that the rear wheels have locked, as the handbrake got locked in to full lock and the driver did not manage to pull up the handbrake interlock plate and pull it back to release.

To me, it appears that the tarmac was wet. (I may be wrong). If that was indeed the case, it would attribute the bus sliding, irrespective of whether there was ABS or not - mainly due to the kerb weight.

As I understand, the handbrake/ foot brake is linked to the pressure value of the brake lines; and when handbrake is engaged, all of the air pressure is released (the brakes in trucks/buses are inverted i.e. always locked and air pressure is used to unlock them).
How can the air pressure be lost and generated that rapidly?
@purohitanuj
All the pressure from the reservoir is not lost with a single brake or handbrake operation.
Only pressure in one line from rear brake cylinder upto the handbrake valve is lost.
As soon as the handbrake lever is flipped back to position, the pressure from reservoir cylinder enters the system, and releases the brakes.
The foot operated regular brake has two valves and a cross split, that is one valve for front RH and rear LH and vice versa, the ABS works only on the regular foot operated brake. here too. As soon as the brake pedal is released the air from reservoir floods back into the actuation pipes.

Haven't read this in full context but prima facie, this looks like very poor reporting. Simply
having more bus services will obviously increase the number of accidents too. These things should only ever be reported as percentages i.e. accident number divided by total number of bus journeys or some such reasonable metric.

The concrete is newly laid and yes it was wet during the accident.

This video of the same accident has footage from another camera from inside the shop. It's a milk parlour and the crates outside contain milk.
The bus driver should have braked earlier as this spot regularly gets bottlenecked due to roadside parking and there is slight curve to the right there.
The shop the bus hit is exactly where the 169A is written in the map.

Saw this in a news channel, apparently 2 persons were deceased and third one is seriously injured and being treated.

That is sad. Crossed this accident this morning around 8:30. Seemed to have just happened and the spot had quite a few bikers who seemed to be helping
Suzuki V Strome 650 Crash in Cunningham Road, Bangalore. Must have been doing some crazy speed. The rider passed away.

Reports say that it happened in the night. Any idea what it rammed into to cause such a tall car like Fortuner to get shredded like this.

Not sure about this accident, but accident photos can be deceptive. After and accident, if people are trapped inside the vehicle, the rescuers might break open the vehicle to get access to the victims.

The news channel mentioned that a lorry was involved, but did not show any visuals of the same.
