John Koko, the bassist-singer with The Makaha Sons, has been hospitalized at Kaiser Medical Center with heart problems.

He underwent treatment Saturday night and is in good spirits, according to his brother, Jerome Koko, who is in the group with Louis "Moon" Kauakahi.

The group canceled two weekend appearances — one in Waikiki, one in Hilo — and is postponing Thursday's Moonlight Mele on the Lawn at Bishop Museum, with a new date to be determined later. The group hopes to resume its tour schedule at the end of the month.

Under doctor's orders, Koko is not accepting visitors at this time.

DAD OF 'HEROES' ACTRESS ARRESTED

LOS ANGELES — The father of "Heroes" star Hayden Panettiere was arrested early yesterday on suspicion of hitting his wife, authorities said.

Alan Panettiere was arrested by Los Angeles County Sheriff's deputies in West Hollywood and detained on suspicion of spousal assault, sheriff's spokesman Steve Whitmore said. He was later released after posting $50,000 bail.

Whitmore declined to name the woman that Panettiere is accused of hitting, but said she reported to deputies that he struck the woman three times with an open hand.

Whitmore said detectives would not release a mug shot of Panettiere.

Los Angeles court records do not indicate any prior charges for the 49-year-old father of Hayden, who plays Claire Bennett on NBC's hit show, "Heroes."

ROCKER SUES OVER INVESTMENT

SAN DIEGO — Former Blink-182 bassist Mark Hoppus sued a father-and-son business yesterday, alleging they pocketed his investment in a venture to install automated checkout machines at McDonald's restaurants.

The lawsuit in San Diego Superior Court says Ed and Jeff Mitchell lined their pockets "to the tune of over $1.5 million." It alleges their company — Missicom LLC of San Diego — does not have any contracts to install the machines to take orders and collect payments at McDonald's or anywhere else.

Hoppus, currently a member of the pop-punk band Plus-44, invested $600,000 in Missicom in October 2003, according to the complaint.

The lawsuit says the Mitchells raised nearly $3.4 million and solicited millions of dollars from "prominent, well-known figures."

Hoppus' attorney, Howard King, said in a news release that other investors included golfer Phil Mickelson and former Blink-182 members Tom Delonge and Travis Barker. After Blink-182 disbanded, Hoppus and Barker formed Plus-44.

MCMAHON FACES ANOTHER LAWSUIT

LOS ANGELES — Ed McMahon is being sued by another creditor.

Westmoore Lending of Huntington Beach, Calif., sued McMahon for more than $275,000 it says the pitchman and former "Tonight Show" sidekick owes from a 2006 loan.

A growing number of creditors say McMahon and his wife, Pamela, owe them money. The other actions have targeted debts incurred for the couple's Beverly Hills home, prescription drugs, credit card debt and attorneys' fees for his daughter's divorce.

The lawsuit filed yesterday in Los Angeles Superior Court does not specify what the McMahons borrowed the money for, but claims they defaulted on the loan in early 2007.

A spokesman for McMahon said yesterday that he hadn't seen the lawsuit.
