Pop singer Adam Lambert has been accused of attacking a photographer in Miami Beach on Friday, celebrity website TMZ.com first reported.

According to a police report posted on the site, the 28-year-old Lambert allegedly became “angry and started running towards him in an aggressive manner” after the photographer began taking unwanted pictures.

“As the victim began to run away, the subject grabbed the victim's backpack where the camera was placed. The subject wrestled the victim to the ground forcefully. A crowd began to gather and the subject fled toward the boardwalk.”

The photographer did not sustain any “bruises or lacerations,” the report concludes.

Lambert, who came out gay last year on the cover of Rolling Stone, responded to the claim on Twitter, where he messaged his followers, “I lost my temper for a sec but wow it felt great lol MIAMI!!!”

In another tweet, he denied the charge: “Battery? Nope. I attempted to grab a camera, no punches were thrown and no one was on the ground … It was literally harmless. If embarrassment is a crime – that's all I'm guilty of.”

Police have yet to determine whether to prosecute Lambert.

Update: This version corrects the mistake that Lambert's first tweet was deleted from his feed.
