LOS ANGELES, California (CNN) - The Drug Enforcement Administration has joined the investigation into whether prescription drugs were involved in the death of singer Michael Jackson, a federal law enforcement official said Wednesday.

The official, who did not want to be identified because he cannot comment publicly on the matter, said DEA agents will be looking at various doctors involved with Jackson, their practices and their possible sources of medicine supply.

Officially, a DEA spokeswoman referred questions to the Los Angeles, California, police department. The police department would not confirm the involvement but said the federal agency is routinely called in such instances.

"We routinely offer assistance to any agency regarding the Federal Controlled Substance Act," said Sarah Pullen of the DEA. "However, at this time, we have nothing further to comment about the death of Michael Jackson."
