AEG President Tim Leiweke tells the Los Angeles Times that City Attorney Carmen Trutanich (Troo-TAN'-ich) used a bully tactic to demand the money, warning he would "go after you guys."
Trutanich says the figure he wants is $2.3 million, not $6 million, and he makes no apologies.
Trutanich tells KNX Newsradio on Thursday morning that he asked AEG to pay for the deployment of 4,000 officers.
The costs involved in July's Jackson tribute at Staples sparked a public backlash as Los Angeles struggled with budget problems. Trutanich has opened an investigation into the costs.
