Among the claims are that the three would give away a pre-determined amount of runs in a given over. Delhi Police Commissioner Neeraj Kumar - who described the arrest as done "with considerable regret and anguish", which sounds like he's a genuine cricket fan - said amounts up to US$100,000 ($123,402) were on offer for just one rum over.
He described signals given by players, such as fiddling with a wristband, or neck chains, or hanging a towel around their waist, which were spotted.
Spot fixing came to prominence most recently in the jailing of Pakistani trio Salman Butt, Mohammad Asif and Mohammad Aamer in 2011 for bowling no balls to order in a Lord's test for a bookmaker the previous year.
What that showed, and this latest slipping batch of arrests, reinforces, is how easy it is to rig a situation within a game. Forget trying to jack up the result of a match; there's moolah to be made over and over during the, in this case, 40 overs. A timely scratch of the left ear, a false start to a runup, a running of a hand through the hair, so simple.
All three Indians have been suspended. Excuse me if my jaw didn't exactly hit the floor when the story broke. The tale of the former great rang loudly.
The bloated excesses of the IPL are distasteful. A friend who talks of the yellow team playing the blue team, rather than by name, has it right. Treat it for what it is.
The financial rewards are too great for the greedy, or weak, to ignore. You can be sure this won't be the only instance of dodgy dealings in the IPL. They're just the first to have had their collar felt.
There are two sides to the IPL. One is dominated by the likes of entertainers such as Chris Gayle, Kieron Pollard, AB de Villiers, MS Dhoni and Mahela Jayawardene. The other, darker side, was centre stage this week.
