"Goodbyes are hard, even for the grownups", Maryam had tweeted with a picture of her children.
Party spokesperson Marriyum Aurenzeb told PTI that police arrested the workers, mostly from Lahore, to stop them from welcoming Sharif at the airport. They would be kept at Adiala jail for 1 day and then would be transferred to Attock Fort.
Over 10,000 police officers have been posted in Lahore for what is expected to be a dramatic homecoming for the three-time prime minister who wants to mobilise his party ahead of general elections on July 25.

Last week, Sharif was sentenced to a total of 11 years in prison and slapped with a £8-million fine (Rs1.3-billion) in the Avenfield properties reference case, while Maryam, his daughter, was sentenced to eight years with a £2-million (Rs335-million) fine.
Meanwhile, the Pakistan Muslim League-Nawaz (PML-N) has made preparations of their own to welcome the former premier and his daughter. Police have virtually put Lahore on lockdown as scores of Sharif's supporters clashed with police in the evening. As per ANI, the PML (N) president said, "We thought Bangladesh is a baggage and it slipped off our hands". "The Election Commission of Pakistan must act and order release of our detained workers".
His return is seen as a public show of acquiescence meant to win sympathy from voters in an election that analysts predict could either spell the downfall of one of Pakistan's most charismatic leaders, or lead to years of civil unrest and political instability.
The National Accountability Bureau (NAB) has already announced that the father-daughter duo will be arrested as soon as their aircraft lands in Lahore and will be sent to Islamabad on a helicopter.
PML-N leaders say authorities have began a crackdown against union council leaders, the street-level party workers who bring out people on the streets.
