Indianapolis Colts owner Jim Irsay must testify in a custody case involving the children of a woman who lives in one of his homes, the Indianapolis Star reported Wednesday.

The newspaper said Irsay was subpoenaed by Greg Martin, who said he is concerned about the well-being of his minor children, ages 17 and 12, when they are in Irsay's presence.

Irsay was arrested March 16 just before midnight and faces two charges of impaired driving. After his arrest, he spent time in a drug rehabilitation facility.

In a June 17 letter to the Morgan County (Ind.) court, Martin stated that his children were in the home of his ex-wife, Jami Martin, on the night of Irsay's arrest. The home, which Irsay bought for $1 million in February, is a few blocks from where he was arrested.

"As a father, I do not want my children subjected to this type of behavior and lifestyle," Greg Martin wrote in a letter to a Martinsville (Ind.) judge, according to the newspaper. He added that "money does not buy morals or self-respect."

Prosecutors allege that Irsay had "oxycodone and/or hydrocodone" in his system and police records said officers "continuously had to support Irsay in order to prevent him from falling over."

Irsay is facing an Aug. 28 trial date on the two misdemeanor charges. Each one carries a maximum penalty of 60 days in jail and a $500 fine.

The Martins, who lived in Martinsville, divorced in January 2013, agreeing to joint custody of the children.

Irsay was divorced in January 2014 after living apart from his wife for more than a decade, according to the newspaper.

Irsay did not respond to an Indianapolis Star request for comment made through the Colts.
