A paparazzo was arrested Thursday for investigation of trespassing while trying to photograph Angelina Jolie's adopted son, said a publicist for her partner, Brad Pitt.

Photographer Clint Brewer, 25, was attempting to take pictures of 4-year-old Maddox at a daycare center the child was attending, Pitt's publicist Cindy Guagenti said in an e-mail.

Brewer was seen hiding in bushes and photographing the church-based establishment shortly before 11 a.m. when security detained him and the property's owner made a citizen's arrest, said Lt. Crystal Miranda of the Los Angeles County Sheriff's Department.

Deputies arrested Brewer on suspicion of trespassing and transported him to the Malibu sheriff's station, where he was being held on $1,000 bail.

No further details were immediately released.

Jolie, Pitt and their brood returned to Malibu two weeks ago after Jolie, 31, gave birth to daughter Shiloh Nouvel Jolie-Pitt in Namibia last month. The couple have two older children, 18-month-old Zahara, adopted from Ethiopia, and Maddox, adopted from Cambodia.

Both Maddox and Zahara's surnames were legally changed to Jolie-Pitt after Pitt, 42, announced his intention to adopt the children.
