Authorities in California have arrested a man who was seen near a golf course owned by President Donald Trump in the Los Angeles area, ahead of the president's visit for a fundraising dinner there.

Jeanine John Taele, 38, was found with a pistol and illegal ammunition at the Trump National Golf Course in Rancho Palos Verdes, investigators say. BBC reported.

According to the Los Angeles Sheriff's Department, he was "observed walking throughout the golf course grounds taking photographs and videos and appearing to monitor security-planning activities".

The arrest took place on Sunday afternoon. Trump is currently visiting California to attend a Republican party fundraising dinner at the course on Tuesday.

Taele is being held on charges of carrying a concealed firearm and possession of armour-piercing/prohibited ammunition.

In a news release, the sheriff's department said Taele was arrested after plainclothes federal agents reported a suspicious person to local authorities during the middle of the day, around 1530 ET (2330 BST).
