Officers from the Los Angeles Police Department's Internet Crimes Against Children Task Force unit arrived at the actor's home in Sunland, California on Tuesday morning (29Dec15) to carry out a search warrant.
He was subsequently taken into custody, where he is due to be booked for the alleged offence, according to CrimeWatchDaily.com.
Representatives for the 33 year old had yet to comment on the news as WENN went to press.
The arrest comes less than a year after Salling reached a $2.7 million (£1.8 million) settlement with Playboy pin-up Roxanne Gorzela, after she sued the star in 2011 amid allegations of sexual battery. She dropped the claim in March (15) after Salling confessed to negligently causing his ex to fall and injure herself during an incident at his home.
