SCALPERS are trying to sell tickets to the Michael Jackson memorial service for up to $US20,000 (,115) each in a move that has divided fans.

As LA courts yesterday revealed three searches had been conducted on the superstar's home in connection to his June 25 death, fans were split over the cost of a spot at the service to be held in Los Angeles early tomorrow (3am AEST).

More than 1.6 million fans registered in the online lottery to win free double passes to the memorial service.

Yesterday, as some fans begged for access, others said they were disgusted some of the 8750 ticket winners were trying to profit.

Fan websites lit up yesterday as word of ticket winners - and eBay and Craigslist scalpers - spread.

A posting on Craigslist read: "I'm willing to sell tickets to the Michael Jackson memorial - best offer will be taken."

Ebay tried to swoop on ghoulish profiteers.

"Any tickets for the memorial service will be taken down," a spokesman said yesterday.

Some of Jackson's followers said they felt repulsed by the greed.

"There are a few eBay sellers already selling the memorial tickets and they have not even been picked to go?" wrote one fan.

"These people are sick, How could they!" wrote another fan.

Organisers have gone to extremes to stop people on-selling tickets, with plans to check IDs before strapping wristbands on fans as they collect their tickets.

But there is nothing to stop winners selling their second bracelet.

"Theoretically, the second wristband can be sold," organiser Michael Roth said.

Police yesterday tried to persuade fans to stay away from Los Angeles' Staples Centre, where up to 700,000 people are expected to congregate.

"You'll be standing in the hot sun on a city street with a lot of other people ... but not within eyeshot of Staples," Assistant Police Chief Jim McDonnell warned .

Hotels around the stadium are filling fast. More than 90 per cent of the Wilshire Grand's rooms are full, up from 60 per cent capacity last week.

"There's a lot of demand right now," said spokesman Marc Loge. "We are going to sell out."

Meanwhile, a Los Angeles Superior Court judge has granted three search warrants on Jackson's rented mansion.

They were performed last Wednesday, a court spokesman confirmed.

Police reportedly want to interview several doctors over Jackson's prescription drug use.
