Demi Lovato’s alleged drug dealer named Brandon Johnson will not face police investigation after the singer suffered a suspected overdose in July.

A source close to law enforcement told TMZ that Johnson will not be questioned by police as an overdose is believed to be a “medical emergency”.

Earlier, Johnson said that the Sorry Not Sorry singer had texted him at 4am, asking him to come over which he took as a request to bring narcotics, leading to his claims they then smoked drugs together.

Johnson was arrested in March, after he was discovered with narcotic substances, $10,000 (Dh36,724) worth of cash and guns, and later arrested in June for possession of cocaine, as well as driving under the influence of alcohol.
