Deutsche Bank exec Brian Mulligan admitted bath salts use LOS ANGELES, Oct. 16 (UPI) -- A Deutsche Bank executive was recorded admitting he used bath salts days before a violent confrontation with Los Angeles police. Brian C. Mulligan, managing director and vice chairman at Deutsche Bank, entered a Glendale, Calif., police station May 13 and told the desk officer he thought he was being followed by a helicopter. The officer was recording Mulligan, who is described as rambling at times during the 11 minute conversation, the Los Angeles Times reported. During the conversation, Mulligan allegedly admits he bought some "white lightning" -- a type of synthetic marijuana generically dubbed "bath salts" -- and snorted it about 20 times. Police reports indicate the officer urged Mulligan to get drug counseling. Three days later, Mulligan found himself involved in a violent confrontation with LAPD officers who described similar bizarre behavior in their report. The officers reported coming across a sweat-drenched Mulligan who they said matched a generic description for a white male attempting to break into vehicles. Officers took Mulligan to a nearby motel at his request. When the officers later came across him again, they said he arched his back, waved his arms, stiffened his fingers like claws and charged them. The police report said the officers responded with force to subdue him. In a lawsuit, Mulligan alleges the officers took him to the motel against his will and beat and detained him to steal money, the Times reported. Mulligan has filed a $50 million notice of claim against the city, a precursor to a lawsuit, but has so far not gone forward with an actual lawsuit.
