New York State Police at Oneonta arrested a 30 year old Oneonta man Friday evening for two counts of the misdemeanor endangering the welfare of a child.  The arrest of Robert Smith occurred after troopers responded to a 911 report of two children running in the middle of the road unattended, near the Speedway gas station in the Town of Oneonta at about 6:32 p.m.  The four and six year old brothers were located by troopers near the Dairy Queen on Chestnut Street in the Town of Oneonta.  An investigation determined that at about 4:30 p.m., the brothers had been left under the care of their father Smith, who lives on Oneida Street.  Responding troopers found the father sleeping at his home unaware that his children had left.  Smith was arraigned in the Town of Oneonta court and was remanded to the Otsego County jail in lieu of $200 cash bail or $400 property bond.
